What does injector circuit low mean?

This trouble code indicates that the powertrain control module has detected a lower reference voltage coming from the number 1 cylinder’s fuel injector than what was specified by the vehicle manufacturer.

What is engine code P0153?

Diagnostic trouble code (DTC) P0153 stands for “ O2 Sensor Circuit Slow Response (Bank 2, Sensor 1).” It checks the oxygen levels of the exhaust leaving the exhaust manifold and the PCM compares its reading with the signals coming from the oxygen sensor 2 behind the converter.

What does the code P0153 mean?

The P0153 trouble code is an indication that the oxygen sensor is not properly regulating the fuel and oxygen levels. When the oxygen sensor switches at a speed that is slower than normal, it causes a slow response between the oxygen sensor and the power control module (PCM).

What causes O2 sensor slow response?

The slow response of an O2 sensor may be due to a sensor that is just getting old and over time may get contaminated with time with carbon and other contaminants that deteriorate the sensor over time.

What are symptoms of a bad O2 sensor?

Here are some of the most common signs that your oxygen sensor is bad.

  • A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.
  • Bad Gas Mileage.
  • An Engine That Sounds Rough.
  • An Emissions Test Failure.
  • An Older Vehicle.

Can you drive your car with a bad O2 sensor?

Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don’t leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.

Fix P0154 Honda

In the case of a Honda, the P0154 error
code indicates that the upstream oxygen sensor on bank 2 is not detecting any circuit activity. Here’s what the dictionary says about it: No activity was detected in the O2 Sensor Circuit (P0154) (Bank 2 Sensor 1). It should be delivering a fast changing reading to the computer when this oxygen sensor is functioning normally.

Should you replace the oxygen sensor or air/fuel sensor to fix P0154?

You may be forced to do so, but do not begin there. Leaks in the air intake duct, which goes from the air filter box to the throttle body, are a common problem with Hondas, according to the manufacturer. Because the airflow is measured by the MAF sensor, which is located near the air filter box, any type of leak will cause all of the oxygen sensor values to be incorrect. This is due to the fact that unmetered air is being drawn into the engine. Because of the MAF sensor, the computer calculates what it perceives to be the right air/fuel ratio.

The computer attempts to rectify the error but is unsuccessful.

If you get a P0154 on a Honda, check the air intake duct first

Remove the air intake duct and shine a light through the pleats to see what’s going on within. If you notice ANY light coming through the duct, it is time to replace it. Never replace an air/fuel or oxygen sensor until you’ve performed this test on the sensor first.

Then test the oxygen or air/fuel sensor

Check to ensure that the sensor heater is receiving battery power as well as a ground for the heating element. Then consult a shop manual to determine the specifications that are permissible. If you’re not obtaining that reading, try something else. Aside from that, Hondas are not fond of universal or off-brand sensors. Replace the sensor with the same model number from Denso or NGK.

P0154 – Meaning, Causes, Symptoms, & Fixes

There was no activity detected in the O2 Sensor Circuit (Bank 2, Sensor 1)

What Does P0154 Mean?

When your vehicle’s oxygen sensor (bank 2, sensor 1) malfunctions, the code P0154 is shown on the dash. An error has been detected by the Engine Control Module (ECM) in that the Oxygen (O2) sensor has come to a complete stop and is no longer reliably monitoring the quantity of oxygen present in the exhaust stream. Because of this inaccuracy in the oxygen sensor, the ECM misinterprets the amount of oxygen and fuel that is being released via the exhaust, preventing it from maintaining the proper fuel ratio.

What Are the Symptoms of Code P0154?

  • The Check Engine Light is illuminated. Increased emissions
  • Excessive smoke from the exhaust
  • A poorly functioning engine
  • Decreased fuel economy

*In certain circumstances, there are no evident unfavorable effects.

What Is the Cause of Code P0154?

  • O2 sensor that is not working properly
  • Faulty heater circuit The presence of frayed or damaged wire
  • There is an issue with the connection at the O2 sensor connector. Engine vacuum leak
  • Exhaust leak
  • Faulty engine control module

How Serious Is Code P0154?- Moderate

However, while this issue code is unlikely to prevent your vehicle from starting, it may cause damage to the catalytic converter over time, which may impair your vehicle’s ability to operate cleanly and effectively. The most typical consequence of this issue code is a reduction in the fuel efficiency of your vehicle.

Code P0154 Common Diagnosis Mistakes

Prematurely changing the oxygen sensor when the problem is really with the wiring or connections, which might have been detected with a visual check instead of the sensor.

Tools Needed to Diagnose Code P0154:

The difficulty in diagnosing and repairing the problem is a two-out-of-five rating.

  1. Check to see if there are any additional codes present in addition to P0154, and then use FIXD to clear your Check Engine Light. Using a visual inspection, check the wire at the O2 sensor for fraying or breakage. Additionally, ensure that the connector has a proper connection and is not corroded. If there are symptoms of fractures or disconnections in the vacuum lines or intake air tube, they should be replaced. If there are any exhaust leaks between the engine and the O2 sensor, these should be checked. Whenever necessary, repair
  2. Examine the voltage for varied voltage between.1 and.95V when the engine is running at normal operating temperature. If this reading is not within specification, it may be necessary to replace the O2 sensor 1 on bank 2. Check for continuity in the cabling from the ECM to the oxygen sensor. If there is continuity and you have already changed the oxygen sensor, there is a possibility that the ECM has an internal defect. Consider replacing the ECM or taking it to a repair shop for a more thorough examination.

Estimated Cost of Repair

If you receive error code P0154, one or more of the fixes listed below may be required to resolve the underlying problem. The estimated cost of repair for each feasible repair includes the cost of the essential components as well as the cost of the labor required to complete the repair, if any.

P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)

Article written by Dale Toalston, an ASE Certified Technician. The O2 Sensor Circuit had no activity detected (Bank 2 Sensor 1)

What does that mean?

This diagnostic trouble code (DTC) is a general powertrain code, which means that it applies to any cars that are equipped with the OBD-II diagnostic system. Despite the fact that they are general, the particular repair processes may differ based on the make and model. The oxygen sensors are crucial in ensuring that the engine runs correctly. It primarily serves to tell the PCM (Powertrain Control Module) of the amount of oxygen present in the exhaust. The PCM then makes use of this information to manage the amount of fuel delivered to the engine and to maintain the correct air-to-fuel ratio.

  • In most cases, it also serves as a foundation.
  • Using this heater, the sensor may be warmed up more quickly, allowing the engine to enter closed loop more quickly, resulting in lower starting emissions.
  • The oxygen level of the exhaust has an effect on the resistance of the O2 sensor.
  • Low voltage is produced by lean exhaust, and high voltage is produced by rich exhaust.
  • Following reaching closed loop, the oxygen sensor should begin switching quickly between rich and lean voltages, about 2-3 times per second, until the engine is no longer running rich.
  • This signal indicates that the oxygen sensor is not functioning properly.


As a general powertrain code, this diagnostic trouble code (DTC) pertains to any vehicle equipped with an OBD-II diagnostic port. The particular repair processes may differ based on the brand and model, despite the fact that they are generally the same. Having suitable oxygen sensors is crucial to the correct operation of the engine. Its primary function is to provide information to the PCM (Powertrain Control Module) on the oxygen content of exhaust. Once this information has been received by the PCM, it is used to regulate fuel injection into the engine and maintain an appropriate air/fuel mixture.

  • The majority of the time, it also serves as a ground The remaining two wires are allocated to the heating element for the oxygen sensor (see Figure 1).
  • It is common for the heating element to be powered by a 12v supply from the power distribution center, in addition to being grounded.
  • On the reference/signal line, this resistance generates a counter voltage, which is used by the PCM to determine whether or not oxygen is present in the exhaust.
  • Depending on the environment, the oxygen sensor can range between 0.9v (rich) and 0.1v (low) (lean).

It is possible that P0154 will be set if the oxygen sensor does not switch correctly or ‘stuck.’ This signal indicates that the oxygen sensor is not functioning properly.

  • Illumination of the MIL (Malfunction Indicator Lamp)
  • Other codes that indicate a rich or lean state may also be present
  • For example, Idle performance is poor, and the vehicle will not idle. Misfiring either at idle or while traveling at motorway speeds
  • It is possible for the engine to emit black smoke from the exhaust. It is possible that fuel efficiency will decline. It is possible to start and then stop


The following are examples of possible reasons of the P0154 code:

  • Bank 2,1 oxygen sensor is faulty
  • There are holes in the exhaust near the oxygen sensor. On the signal circuit, make a short to the voltage or ground
  • In the signal circuit, there is an open or a high resistance. The wiring harness is chafing and rubbing against the exhaust components. A leaky oxygen sensor connector due to water or oil penetration
  • A broken lock or unsecured terminals on the oxygen sensor connector
  • An oil or coolant contaminated oxygen sensor

Possible Solutions

Initialize the engine and get it up to working temperature, then check to see if the engine has reached closed loop operation. Then, using the live data feature on a scan tool, check the voltage reading of the Bank 2,1 oxygen sensor. Is the switch functioning properly? If this is the case, the problem might be caused by an intermittently defective sensor or, more likely, by a wiring issue. Visually inspect the O2 sensor wire and make any necessary repairs. Is it possible that the voltage for the Bank 2,1 oxygen sensor appears to be ‘stuck’ and is not moving?

  • If the sensor begins to flip after a period of increased idle, physically inspect the exhaust for any holes or corrosion that might be impacting the voltage reading near the O2 sensor.
  • If the Bank 2,1 oxygen sensor does not appear to be switching, turn off the engine and remove the Bank 2,1 oxygen sensor from the vehicle.
  • The voltage value should be low at this point (about 0.1v).
  • Make any required repairs.
  • If the voltage measurement is not low (about 0.1v) when you connect the signal wire to the ground wire, you should remove the jumper wire.
  • With the KOEO and O2 sensor disconnected, it should have produced around 0.5 volts.
  • Make any required repairs.
  • Unplug the PCM connector and conduct an Ohm test on the signal circuit and ground circuits if you do not have a 0.5 volt reference value.
  • Excessive resistance should be repaired.
  • When it comes to eliminating the chance of a short or open anywhere, it may be required to cut the signal line.
  • If there is no reference voltage coming out of the PCM, it will be necessary to detect a defect with the PCM.

Honda Odyssey slow acceleration causes and how to fix it

The frustration of driving your Honda Odyssey with engine hesitation or slow acceleration is compounded by the fact that it may also be dangerous, especially while passing or crossing an intersection. Sluggish acceleration is an indication of a more serious problem with your Odyssey that needs to be addressed immediately to prevent further damage to your vehicle. Photograph of the Honda Odyssey by Betto Rodrigues / Shutterstock The most typical reasons of sluggish acceleration in a Honda Odyssey include a clogged air filter, a filthy mass air flow sensor (MAF), a clogged fuel filter, a blocked fuel pump, a malfunctioning oxygen sensor, a dirty throttle body, worn spark plugs, and a clogged catalytic converter, to name a few examples.

1. Clogged air filter

If the air filter in your Honda Odyssey becomes clogged, it may have a detrimental impact on the performance of the engine. This is because less air goes through the filthy filter, suffocating the engine and reducing its efficiency. Ultimately, this leads to an increase in fuel usage. In the worst case scenario, if the air filter is significantly clogged, the engine may stall completely. It only takes a few minutes and does not necessitate any specific skills to replace the filter in your Odyssey.

2. Dirty or faulty mass air flow sensor (MAF)

Your Honda Odyssey’s engine performance can be negatively affected if the air filter is clogged, since less air goes through the clogged filter, suffocating the engine and causing it to overheat. As a result, fuel consumption ultimately increases.

A severely blocked air filter might cause the engine to stop in the worst case scenario. It only takes a few minutes and does not necessitate any particular skills to replace the filter in your Odyssey. Thus, this should be the very first item you look at.

What happens when MAF sensor malfunctions in Honda Odyssey?

It is not possible to deliver accurate measured results to the Odyssey’s control unit if the MAF sensor is damaged or clogged with debris. Because it is no longer possible to compute the ideal amount of fuel, either too little or too much gasoline is injected into the combustion chambers, resulting in a loss of efficiency. The engine is either too ‘lean’ or too ‘rich’ in its operation. The engine warning light in the instrument cluster may glow as a result, and a diagnostic device can be used to determine the source of the problem.

What causes MAF sensor to fail in Odyssey?

The mass air flow sensor is a replaceable component. While driving your Odyssey, it is possible that the engine control unit will get more erroneous numbers as the mileage on the vehicle grows. Because of a notable decrease in performance and high mileage, a bad MAF sensor should be looked at immediately. However, the sensor may have a failure sooner rather than later. When driving at a high rate in heavy rain, water can occasionally get through the air filter, causing the MAF sensor to malfunction and cause significant damage to the vehicle.

How to check if the MAF sensor is bad in Honda Odyssey?

The reading of fault codes from a diagnostic instrument is a generally dependable procedure. It is possible that the mass air flow sensor is malfunctioning if the OBD2 scanner reads the following codes: P0100, P0101, P0102, P0103 or P0104. It is possible, however, that there are no error codes present. In the event of a lingering uncertainty, the sensor may need to be replaced. However, this should only be done after a thorough investigation, since the MAF sensor may not be to blame for the symptoms of poor acceleration that you are experiencing in your Odyssey.

Can I clean a dirty MAF sensor in Honda Odyssey?

Cleansing the mass air flow sensor may be necessary in some instances to ensure that the sensor measures the right numbers once more. However, extreme caution should be exercised in this situation because the sensor portions are extremely sensitive to touch. To remove your Odyssey’s MAF sensor from its housing, locate it and unhook the electrical connectors that connect it to the rest of the vehicle’s electrical system. Spray at least ten spurts of MAF cleaner onto the sensor and allow it to air dry for an hour or until it is totally dry before replacing the sensor.

Recommended video:

Note (MAP Sensor): If you are unable to locate a MAF sensor in your car, it is conceivable that your vehicle does not have one, particularly if it is an older vehicle with limited functionality. A mass flow rate is determined by the control unit instead, and this is done by analyzing data collected by the MAP sensor. A defective MAP sensor exhibits symptoms that are almost identical to those of a faulty MAF sensor.

3. Clogged fuel filter

If the gasoline filter in your Honda Odyssey becomes clogged, not enough fuel will be able to enter the engine. When the car accelerates, this results in a loss of power and jerking of the vehicle. When there is insufficient gasoline delivery, the worst case situation is that the engine shuts down while you are driving. A shortage of fuel problem can be detected by the control unit in the Odyssey, which will cause the engine check light to illuminate in that situation.

When you attach an OBD2 scanner to your car, you may receive the error code P0087, which indicates that there is a problem with the gasoline delivery system.

How does the fuel filter get clogged in Odyssey?

When a gasoline filter is installed in your vehicle’s fuel tank, it is intended to prevent rust particles and other debris from entering the engine, where they might cause costly damage. If you don’t keep up with the maintenance plan for your Odyssey and don’t change the fuel filter on time, the permeability of the filter decreases, and the fuel pressure in the engine diminishes as a result of this. However, if the gasoline filter becomes too clogged, the engine’s performance will suffer as a result of the lower fuel flow.

4. Clogged catalytic converter

The gasoline filter is intended to prevent rust particles and other debris from entering your car’s fuel tank and entering the engine, where they might cause costly damage to your vehicle. Keeping up with the maintenance plan of your Odyssey and changing the gasoline filter on a regular basis will help to reduce the permeability of the filter and the amount of fuel pressure in the engine. However, if the gasoline filter becomes too clogged, the engine’s performance will suffer as a result of the lower engine performance.

What are the signs of bad catalytic converter in Honda Odyssey?

The following are common symptoms of a clogged catalytic converter in an Odyssey: irregular engine operation, unusual exhaust gas odor, poor fuel economy, the engine check light illuminates, limited performance above a certain speed or loss of performance, and occasionally rattling noises from the exhaust.

How long does the catalytic converter last in Honda Odyssey?

There are a variety of elements that influence its service life, but the catalytic converter in the Odyssey normally lasts between 70,000 and 100,000 miles on average. In other cases, it may fail considerably sooner than this owing to other issues in the vehicle, such as misfires in the engine, poor air-fuel mixtures, a malfunctioning oxygen sensor, or coolant in the combustion chambers, which can all contribute to catalytic converter failure.

5. Faulty oxygen sensor

The oxygen sensor in the Honda Odyssey continually checks the level of pollutants in the engine’s exhaust fumes and transmits the information to the control unit, which continuously changes the air-to-fuel ratio in the engine to ensure that the engine runs efficiently. It is possible for the oxygen sensor to develop a malfunction, which will result in inaccurate readings being sent to the control unit. This can cause delayed acceleration, power loss, irregular idling, engine slowness, and even stoppage.

Can a bad O2 sensor lead to catalytic converter failure in Honda Odyssey?

Oxygen sensors that have failed are the most common cause of catalytic converter failure. If you believe that your O2 sensor is malfunctioning, you should act quickly and have it examined by a qualified mechanic. Catalytic converters, on the other hand, may easily cost you more than a thousand dollars to replace, but oxygen sensors are quite inexpensive in comparison.

How to check for faulty oxygen sensor in Odyssey?

Catalytic converter failures are most commonly caused by faulty oxygen sensors.

As soon as you believe that your oxygen sensor is malfunctioning, you should get it examined by a qualified technician. Catalytic converters, on the other hand, may easily cost you more than a thousand dollars to replace, but oxygen sensors are quite inexpensive.

A clogged throttle body in your Honda Odyssey might also contribute to the vehicle’s poor acceleration. Among the most typical symptoms of a filthy throttle body are poor engine performance, an inconsistent idle, the engine responding poorly to changes in the accelerator pedal position, and the engine sputters or stalls. Typically, a throttle body becomes filthy after 70,000 miles, which is especially true for automobiles that are frequently used in stop-and-go city traffic. However, an air leak in the intake system or an engine problem might cause the throttle valve to become contaminated much sooner.

The throttle valve is responsible for controlling the amount of air that is supplied to the internal combustion engine.

7. Faulty throttle position sensor (TPS)

The throttle position sensor, sometimes known as the TPS, is responsible for determining the angle at which the throttle valve opens. The information gathered is relayed to the control unit, where it is used to calculate the amount of fuel that will be required. Engine jerks, RPM variations when the vehicle is parked, and a gradual drop in speed after the driver releases the accelerator pedal are all common signs of an incorrectly functioning throttle position sensor in the Odyssey. If you encounter any fault codes ranging from P0120 to P0124 on your OBD2 scanner, it indicates that the TPS sensor is malfunctioning.

8. Fuel pump malfunction

When your Honda Odyssey is operating, the fuel pump functions similarly to a beating heart, pumping gasoline into the engine to keep it running. A faulty fuel pump can cause erratic or reduced acceleration, poor engine starting behavior, jerking or stalling of the engine while driving, as well as a reduction in fuel economy. Fuel pumps are not inexpensive; thus, before replacing one, make certain that the problem is with the fuel pump itself. Leaks or contamination inside the fuel pump are two of the most common reasons of a faulty fuel pump in your Odyssey, both of which can cause the engine check light to illuminate.

9. Bad spark plugs or ignition coils

If the spark plugs in your Odyssey are not producing enough sparks, the engine will no longer perform at its peak. This is typically shown as a decrease in performance as well as an increase in fuel consumption. Other signs of engine trouble include jerking or squealing while driving, as well as the possibility of the engine completely shutting down. Driving with a damaged spark plug increases the danger of incurring highly expensive consequential damage, such as catalytic converter failure, if the problem is not addressed.

It is the ignition coils on your Odyssey that are responsible for amplifying the relatively modest battery voltage of 12V to a very high voltage of hundreds of thousands of volts for the spark plugs.

They are a component of the ignition system on your Odyssey. If there is a problem with the ignition coil, it might produce poor sparking, which can lead to poor engine performance. The symptoms of a faulty ignition coil are similar to those of a damaged spark plug, with a few exceptions.

10. Dirty fuel injectors

Fuel injectors are a component of the fuel delivery system that sprays fuel in the form of a high-pressure mist whether the vehicle is in motion or stopped. Over time, they can get blocked as a result of the hydrocarbons, silt, and other substances present in the gasoline. When this occurs, the necessary amount of gasoline cannot be supplied to the combustion chamber at the proper pressure. Consequently, the engine will not start. Slow acceleration, rough idling, uneven engine performance, higher fuel consumption, engine reluctance, and misfiring are all signs of blocked fuel injectors in a Honda Odyssey, according to the manufacturer.

Is it safe to use fuel injector cleaners in Honda Odyssey?

Cleansing the fuel injector nozzles with fuel additives nearly always results in improved injection behavior because the additive dissolves the deposits that have accumulated on the injectors. However, before using your chosen injection system cleaner in your Odyssey, it is suggested that you check with Honda to see if it has been approved for use. The reason is that the additive is placed into the gasoline tank and travels through the entire fuel system and into the engine. Some injector cleaners might cause harm to the oxygen sensor if they are used improperly.

11. Clogged engine oil filter

The engine oil filter in your Honda Odyssey is responsible for ensuring that the engine oil is clear of dirt particles, metal shavings, soot, and unburned gasoline, hence preventing engine damage. If the filter becomes clogged, it might cause the engine to splutter, with the amount of sputtering increasing the quicker you drive. However, even though most oil filters are equipped with a bypass valve or pressure relief valve, which activates when the filter gets blocked after it has not been updated in a timely manner, the bypass valve can malfunction in rare instances.

12. Transmission problem

Slow acceleration in your Odyssey can be caused by a failure in the gearbox, which is also possible. This intricate component is responsible for transmitting power from the engine to the wheels and is thus quite difficult to understand. There are several gears that work in conjunction with one another. Sooner or later, this friction causes wear on the components, which is especially noticeable if your Odyssey has logged a significant number of kilometers or if you haven’t changed the transmission fluid on time.

13. Worn piston rings or valve seals

The piston rings of the Honda Odyssey’s internal combustion engine serve as a sealing device between the pistons. This is accomplished by the use of valve seals and piston rings, which restrict engine oil from entering the combustion chamber. When the piston rings get worn or damaged, the engine’s combustion chamber loses pressure, which causes the engine to shut down. Due to the inability of the piston to properly compress the fuel and air combination, the engine’s power is diminished.

With good engine care, piston rings may easily last for more than 150,000 miles. The following are the most prevalent signs of worn piston rings in an Odyssey: blue colored smoke coming from the exhaust, a lack of acceleration power, high oil consumption, and engine misfiring.

14. Blown head gasket

Engine block and cylinder heads are sealed together by a head gasket, which is responsible for providing that seal. Its purpose is to keep the combustion gases contained within the cylinders and to prevent coolant or engine oil from leaking into the cylinders during the engine’s operation. Leaks in the head gasket can result in a variety of issues, including poor engine performance and/or overheating, depending on the situation. However, with proper engine maintenance, head gaskets can last for more than 100,000 miles before needing replacement.

How to check if head gasket is leaking in Odyssey?

In order to check for a leaking head gasket in your Odyssey, you do not need to take it to a mechanic. It is possible to purchase test kits on the market that require you to simply put a tube filled with colored liquid into the radiator (instead of the radiator cap) and then start the engine. If the color of the liquid changes, this indicates a leak in the head gasket.

Use OBD2 scanner for diagnosis

A fault diagnosis, which is possible since the Honda Odyssey is equipped with on-board diagnostics (OBD), can offer preliminary clues as to where the defect is located. OBD2 scanners are currently available in a number of different configurations. It is possible to utilize a standalone diagnostic equipment (such as the one seen above) or an OBD2 adapter that communicates with a smartphone app over Bluetooth or WiFi. It is necessary to first connect the diagnostic tool to your Odyssey before you can begin troubleshooting.

Turn on the ignition while the tool is still attached.

It is critical that you input this information exactly as it appears on the screen; otherwise, the search results may be erroneous.

Because some OBD codes are exclusive to a particular manufacturer, the scanner will be able to provide you with more accurate information if you provide it with additional information about your Odyssey.


There are a variety of reasons why your Honda Odyssey’s acceleration is not performing as expected. When trying to figure out what’s wrong, it’s best to start with the most obvious issues, such as a problem with the air intake or fuel supply. In any case, it is recommended that non-technical people attend a workshop. Having your vehicle diagnosed by an experienced technician will save you time and money in the long run.

Honda Accord P0154: O2 Sensor → No Activity Detected Bank 2 Sensor 1

P0154 is a problem code that is seen rather frequently. Its definition is general, which implies that it applies to any car using OBDII technology, regardless of manufacturer (Honda Accordor not).

In other words, the PCM/ECM is not picking up on any action from the sensor. There are a variety of possible causes for this code to fail. These include a faulty oxygen sensor, a blown hot element fuse, and wiring difficulties, among other things. We’ll go through each of them in detail below.

P0154 Definition

P0154: No activity detected by the oxygen sensor. Bank 2 Sensor 1 is located on the second floor of the bank. The oxygen sensor in the Accord’s exhaust is used by the computer to determine the quantity of O2 gases present in the exhaust. It makes use of this information to fine-tune the engine on the fly. When this oxygen sensor does not provide a signal, the engine will not be able to operate at peak efficiency, resulting in the appearance of the dreaded check engine light on the dashboard. P0154 has an impact on Bank 2 Sensor 1.

  1. As a result, Bank 2 can be located on either side of the engine depending on the model year and engine.
  2. P0154 will only have an impact on engines that are configured in the ‘V’ configuration.
  3. Sensor 1 will be the first in a series of sensors to be installed.
  4. This voltage should alter when the engine warms up, according to the manufacturer.

P0154 Symptoms Honda Accord

The service engine soon light will most likely be the sole symptom of P0154 in the majority of instances. However, there may be other signs and symptoms. These are some examples:

  • Reduced fuel consumption
  • Stalling engine
  • Increased exhaust smell
  • Black color emanating from the tail pipe
  • Misfire

Honda Accord P0154 Causes

It is possible for many different reasons for P0154 to be thrown in the Accord. Here are some examples. Here is a list of the most prevalent probable causes of P0154 in general, organized by type:

  • Wiring – Bank 2 Sensor 1 is not going to be very tough to locate the most of the time. Inspect the harness at the point where it connects to the oxygen sensor with a flashlight. Check to see that the pins are in excellent condition and that the harness is not fractured when it is installed. Make sure that the wire is not frayed or shorted as well throughout this inspection process. YouTube video on how to check for a short
  • Bad O2 Sensor – The oxygen sensor might malfunction on its own. This is a common source of the error code P0154. Putting it back in without first checking the wire that leads to and from it is a gamble that will almost always pay out, but it’s still a good idea to check your harness connections and inspect it first
  • P0154 is caused by an exhaust leak, which can be found in the exhaust system. It should be possible for you to listen for it and locate it
  • It is possible that a leak in the intake manifold is the source of the P0154 code. When an intake leak occurs, it frequently has an impact on the vehicle’s ability to idle properly. Learn how to test an intake manifold at Coolant Temperature Sensor — A faulty coolant temperature sensor will result in the error code P0154. It is possible to disrupt the feedback loop between the engine’s computer and the temperature sensor if the engine’s computer receives incorrect information about how warm it is. Fuse in the heater circuit is blown


There are a variety of difficulties that might cause the Honda Accord to display the P0154 code. The O2 sensor or the wiring to it will be the most common source of failure.

Honda Pilot Check Engine Light Codes

When the check engine light shines on your vehicle’s dashboard, it may be rather frightening to see that small light suddenly illuminate, but in truth, it is not anything that should drive you to shut down in panic right immediately. If you hear the phrase diagnostic trouble codes (DTC), this is simply another name for the codes that appear on your dashboard when your engine is running. Your Pilot’s ECM (electronic control module), which is also known as the OBD (on-board computer diagnostic system), stores these vehicle computer codes.

The fact is that, while it may seem intimidating at first, learning how to do simple diagnostics can provide you with valuable information about your car as well as allow the Check Engine Light to do what it was intended to do: serve as a guide.

Unfortunately, an illuminated Check Engine Light is not usually accompanied by immediately noticeable and helpful car symptoms. Because there are hundreds of different OBD codes, there are also hundreds of conceivable causes for the indicator to be illuminated, including the following:

  • Emissions control problems
  • O2 sensor failure
  • Faulty spark plugs
  • Problems with the fuel and air metering systems
  • Gas cap that is either loose or missing
  • An old battery
  • Problems with transmission
  • Problems with the computer’s output circuit
  • Faults with the ignition system

This is why it is critical for someone who does not have a great deal of automotive expertise to refrain from making assumptions about what a code indicates. If the engine light turns on as a result of an urgent problem, you run the danger of further harming your vehicle if you do not address the problem immediately. When your check engine light illuminates, you should have it checked out by a qualified Honda repair as soon as possible. Now is the time to call Coggin Honda Fort Pierce at 7725772585, or you can book your check engine light service online right now!

Is it safe to drive your Honda Pilot with the check engine light on?

This is a difficult topic to answer because the degree of the problem varies from person to person and from situation to situation. If the underlying problem is a small one, such as a loose gas cap, the vehicle should be covered while the problem is resolved. The check engine light will normally remain illuminated for an extended period of time. A mixture in the vehicle’s performance might be an indicator of a more serious problem. If your Honda Pilot’s check engine light is on and flashing, this indicates that there is a serious problem with the vehicle, and it is suggested that you have it serviced as soon as possible.

Alternatively, slow down and bring your Honda to one of our qualified experts as soon as is reasonably possible.

What Does the Check Engine Light Mean?

The check engine light on your Honda Pilot is one of the most frequently misinterpreted lights or indications on the vehicle. The check engine light is a feature of the onboard diagnostics system, and it can be shown in a variety of ways depending on the vehicle. An engine symbol, a message such as ‘Check Engine,’ or a mix of the two are all possible with a check engine sign. Depending on the color of the light, it will either be amber or red. It is a component of the diagnostics system present in your car.

Some of these tasks include adjusting the ignition timing of an automatic gearbox, managing the engine speed, and applying stability control, to mention a few examples.

It might be anything as easy as your gas cap being loose, or something as catastrophic as your engine knocking out of whack.

It is possible for an engine to misfire due to a faulty, outdated, or filthy spark plug.

If your check engine light is illuminated, please contact our unit of automotive specialists at Coggin Honda Fort Pierce immediately.

What could cause the check engine light to come on in a Honda Pilot?

Your gas cap might be loose or need to be replaced if your check engine light turns on. If this is the case, tightening or replacing your gas cap could solve the problem. On the other hand, your vehicle’s check engine light might also be an indication of a significant malfunction that could cause serious damage to your engine and result in a large repair expense. The check engine light will either glow or blink depending on your vehicle’s make and model. A constant glow normally signals something less serious, however a flashing check engine light indicates that your vehicle’s engine is in significant condition and that quick assistance is required to fix the problem.

The following is a list of the most typical reasons why your check engine light may illuminate:

  • Your gas cap might be loose or need to be replaced if your check engine light turns on. If this is the case, tightening or replacing your gas cap could resolve the problem. Furthermore, the check engine light might be a warning sign of a major problem that could cause catastrophic damage to your engine and result in a significant repair price. The check engine light will either glow or blink depending on the make and model of your vehicle. Typically, a continuous glow suggests something less serious, but a flashing check engine light signals that your vehicle’s engine is experiencing major problems and that emergency assistance is required. Our recommendation is that you not drive your Honda Pilot if the check engine light is on and to arrange Honda servicing as soon as possible. Listed below is a list of the most typical causes of your check engine light to illuminate:

Honda Pilot Check Engine Light Flashing

We know from years of offering Check Engine Light Diagnosis Service that there are several typical explanations for an illuminated Check Engine Light, including something as simple as a loose gas cap, despite the fact that there are several probable causes. Some of the other typical causes of a Check Engine Light include a problem with the fuel injection system, a bad head gasket, a filthy mass airflow sensor, a damaged oxygen sensor, a faulty emissions control device, or a set of defective spark plugs, to name a few.

When this occurs, the Check Engine Light is turned off, and you may walk out of the repair shop certain that your Honda problem has been resolved.

In order for the sensors to continuously monitor situations, they must also communicate data to the electronic control unit.

However, this is the limitation of the Check Engine Light – it will not tell you what is wrong with your vehicle or what you need do to fix it.

In such case, Coggin Honda Fort Pierce offers a Check Engine Light Diagnosis Service that pinpoints the source of the problem and provides you with a recommendation on what to do next from a Highly Qualified Service specialist.

How much does it cost to get the engine light checked?

There are a variety of issues that can cause the check engine light to illuminate, from a loose gas cap to a more serious failure such as a bad catalytic converter or a problem with one of the car’s oxygen sensors. It is critical to get a quick code reading and diagnosis to determine what is wrong with the car. The intermediate cost of a check engine light diagnosistesting is typically between $88 and $111, depending on the location. The fantastic news is that Coggin Honda Fort Pierce provides comprehensive multi-point checks and free diagnostics, in the majority of situations, to assist in determining the source of your check engine light.

Will the check engine light reset itself?

When the problem or code that caused the check engine light to illuminate is resolved, the Honda Pilot’s check engine light will normally turn off by itself. For example, if a loose gas cap was the reason of your check engine light going on, once the cap is tightened, the light will turn off by itself within a few minutes. Similarly, if your catalytic converter is failing and you’ve been doing a lot of stop-and-go driving, the check engine light may have come on as a result of the large amount of time the converter has been put through its paces.

If you exceed that limit and the indicator remains on, you will need to return your vehicle into Coggin Honda Fort Pierce so that the light and code can be double-checked and the light and code may be reset.

How many miles can you drive with the check engine light?

if your check engine light is illuminated, we recommend that you pull over and contact Coggin Honda Fort Pierce for assistance in determining if your vehicle is safe to commute in or whether we recommend a tow truck be dispatched. Attempting to comprehend the code and then planning your approach appropriately is the most prudent course of action. It might be anything from a faulty sensor to faulty plug wires that require replacement. Because each check engine code has a different level of severity, it is impossible to forecast how many miles you will be able to drive while the warning light is illuminated.
