Code P0132 means the catalytic chamber is not working at optimum efficiency, which can translate to poor combustion. Your car will end up using more fuel to provide the same power required to turn the engine. Experiencing a dip in fuel efficiency is a common indicator of faulty PCMs and diagnostic trouble codes.
What causes a P0132 code?
Code P0132 is triggered when the PCM detects that your heated oxygen sensor reading is too high. This happens when the oxygen sensor voltage stays above a certain threshold for a select amount of time. The code is also triggered if the air-fuel ratio stayed in a rich-biased condition for too long.
How do you fix a high voltage O2 sensor?
The number one most common repair for this problem is replacing the O2 Sensor itself. Another repair would be to replace the wiring or connection for Bank 1, Sensor 2. If the catalyst is the problem, replace the catalytic converter. Replace the fuel injector if it is leaking.
What causes O2 sensor high voltage?
The high voltage condition from the O2 sensor is indicating a lack of oxygen in the exhaust or other related problems, such as a leaking fuel injector or a broken up catalyst inside.
What causes low voltage on O2 sensor?
The voltage output from the O2 sensor may be due to exhaust leaks causing the O2 sensors to give low output voltages. The ECM cannot correctly control the fuel-to-air ratio of the engine fuel mixture if any O2 sensor is malfunctioning.
How do I know if I need a new O2 sensor?
The tell-tale signs of a failing oxygen sensor include the engine misfiring or your vehicle running roughly or irregularly during idle. Additionally, there are other engine performance issues associated with a failing oxygen sensor such as stalling, hesitation, and loss of power.
Can a O2 sensor cause a car to cut off?
So yes, a bad O2 sensor can cause your car to stall.
What does a high voltage code mean?

The P0132 Trouble Code, How To Deal With It
It is one of numerous diagnostic trouble codes (DTC) that may be found in a car’s computer and is represented by the code P0132. All automobiles are equipped with computer modules, which are collectively referred to as PCM (powertrain control module), and which include the ECU (engine control unit) and TCU (transmission control unit) (transmission control unit). The brain computers in automobiles are in charge of monitoring and improving the functioning of the engine and gearbox. They do this through the employment of numerous sensors and the transmission of inputs that can result in the triggering of fault codes.
When there are engine problems, the PCM maintains a number of trouble or error codes that are activated.
What does code P0132 mean?
The P0132 error code is defined as a high voltage bank in the sensor circuit of the sensor circuit. Whenever the oxygen sensors in bank 1 (bank1 o2 sensor1) record high voltage for a lengthy period of time, this code is generated. The low voltage oxygen sensor circuit, also known as the upstream oxygen sensor circuit, refers to the oxygen sensors that are located before the catalytic chamber in a normal single bank engine. The oxygen sensors that are inserted after the catalytic chamber, also known as the downstream o2 sensor, are referred to as the o2 sensor2.
As a result, it is preferable to resolve the P0132 error code as soon as possible rather than later.
Causes and symptoms of P0132 trouble code
Circuit high voltage bank1 sensor1 is not regarded to be a significant problem since it can be resolved by following a few easy actions. Hiring an expert mechanic who can use the OBD II scanner to reset any PCM error codes and locate the source of the problem is a good idea. While monitoring the sources and symptoms of the issue code, it is critical to keep an eye on the situation. The following are some of the most prevalent reasons of a P0132:
- A shortfall in the bank There are only one sensor and one heating circuit. Connectors and wires for oxygen sensors that are broken, corroded, or exposed Problems with the wiring harness
- Extremely high temperatures in the fuel
Despite the P0132 error number, it is still possible to use your vehicle. Some drivers find it difficult to recognize the code that has been established, despite the fact that this is often the work of a mechanic. The following are some of the most typical symptoms of code P0132: The check engine light is illuminated. Aside from the check engine light, you may not notice any other signs of a problem in some circumstances. In the event that this light shines on your dashboard, it indicates that there is an issue with the engine or gearbox.
- Except if your dashboard has illumination problems, a P0132code will cause the check engine light to illuminate.
- The code P0132 indicates that the catalytic chamber is not operating at peak efficiency, which might result in poor combustion performance.
- It is typical to notice a decrease in fuel economy when PCMs and diagnostic issue codes are malfunctioning.
- You will begin to notice engine performance concerns as a result of inefficient combustion and less-than-optimal catalytic converter operation, which can vary from lower power to increased gallons per mile.
- Emissions have increased.
- As a result of insufficient fuel combustion and leaks inside the system, this occurs.
- How to resolve the P0132 error code Code P0132 high voltage bank1 sensor1 problem code diagnosis and repair needs the use of an OBD2 scanner and the expertise of a professional.
Typically, the mechanic will adhere to a set of standard operating procedures established by the manufacturer.
All codes must be reset in order to clear the P0132 and turn off the check engine light.
Viewing real-time data from the OBD-II scanner in order to check the voltage level entering the oxygen sensors upstream.
Checking the wiring harness of the oxygen sensors to see if any wires or connections are exposed or damaged.
The first step is to repair or replace any worn-out or broken oxygen sensor wires that have been discovered.
In most circumstances, unless the oxygen sensors are broken, they will not need to be replaced.

P0132 Code – Meaning, Symptoms, Causes (& How To Fix)
It is possible that the O2 oxygen sensor is malfunctioning if the powertrain control module (PCM) displays the error number P0132 on its display. More precisely, if the PCM detects that the O2 oxygen sensor voltage is more than 450 millivolts for a period of more than twenty seconds, the error code P0132 will be generated. P0132 is an acronym that stands for O2 Sensor Circuit High Voltage (Bank 1 Sensor 1) Speaking about oxygen sensors, here’s what you need to know: As part of the combustion process, they are tasked with monitoring the quantity of oxygen present in exhaust gases as they transit through the process.
Any malfunction with theO2 oxygen sensor will impair the operation of the vehicle and will result in the occurrence of error code P0132 being displayed.
Although error code P0132 necessitates immediate attention, it is possible that no symptoms may manifest themselves when the code is activated. However, if the problem is left unattended for an extended period of time, the driver may likely encounter the following symptoms:
- However, even though error code P0132 demands immediate attention, it is possible that no symptoms will manifest themselves when the code is activated in some circumstances. If, on the other hand, the problem is ignored for an extended period of time, the driver may likely suffer the following symptoms: a.
Possible P0132 Causes
The following are some of the probable causes of the P0132 problem code to occur:
- Damaged oxygen sensor
- Damaged mass airflow sensor
- Increased fuel pressure
- Malfunctioning engine coolant temperature sensor
- Defective PCM
- PCM requires a software update
- Wiring that is faulty
Possible P0132 Solutions
The following procedures can be taken if you are certain that the P0132 error code is present and that it is causing the problem. We recommend that you clean and maintain the oxygen sensor prior to changing it, as well as inspecting the intake manifold before doing so.
- In addition to replacing the O2 oxygen sensor and the mass airflow sensor, troubleshooting the fuel pressure valve, replacing the engine coolant temperature sensor, and repairing or replacing the faulty PCM are also options. Make the necessary repairs to the faulty wire connections.
How to Diagnose the P0132 Code?
When diagnosing the P0132 error, it is critical that the automobile battery charger be connected to the computer. The automobile battery charger guarantees that the battery does not lose its charge throughout the diagnostic process. It is critical to maintain the battery’s state of charge at its maximum capacity; otherwise, a low voltage might result in the generation of further error codes.
Connect the OBD2 Scanner
If the P0132 error code is being diagnosed, it is critical that you have the OBD2 scanner on hand. The OBD2 scanner may be used to read and monitor error codes, as well as to record real-time data from the vehicle. There are two types of OBD2 scanners: a standard code reader and an advanced code reader (or advanced scanner). The latter is more costly, but it has great features for correcting mistake codes. It is recommended.
Check Oxygen Sensor Wiring Harness
Before replacing the oxygen sensor, physically check the wire harness that surrounds the sensor and make any necessary repairs. Sometimes an error code is formed as a result of defective or damaged cable connections, and the error code will be erased if the cable connections are repaired.
Check the O2 Oxygen Sensor Voltage
A digital voltmeter should be used to measure the output voltage at the O2 oxygen sensor. Sensor voltage signals that range between 100 mV to 900mV (0.10 to 0.90V) show that the O2 oxygen sensor is in perfect working order. It is possible that the sensor is faulty if the reading falls outside of the prescribed range of values.
Check for Ground Wiring
Using a digital voltmeter, measure the output voltage of the O2 oxygen sensor.
Sensor voltage signals that range between 100 mV to 900mV (0.10 to 0.90V) show that the O2 oxygen sensor is in proper working condition. It is possible that the sensor is faulty if the reading falls beyond the prescribed range.
How to Replace the O2 Oxygen Sensor
It can be a challenging process to replace the O2 oxygen sensor on your car, but if you enjoy delving into the inner workings of your vehicle, you can do it yourself with relative ease.
Step 1: Turn on the engine
It is recommended that you start the engine and let it run for a few minutes before proceeding.
Step 2: Disconnect the Battery’s negative terminal
The engine should be turned on and allowed to run for a few minutes before proceeding.
Step 3: Locate the O2 Oxygen Sensor
Find the O2 oxygen sensor, which is placed in front of the catalytic converter, and then go to the next step. It has a similar appearance to a spark plug. If you are having trouble locating it, examine your vehicle’s owner’s handbook.
Step 4: Remove the electrical connection
Unplug the oxygen sensor’s electrical connection from the wall outlet. To push the tab into place, you will need a screwdriver. Then, carefully slide the connection out of the way.
Step 5: Remove the sensor
Using a socket wrench, carefully detach the sensor from its mounting bracket.
Step 6: Install the new sensor
Installation of a new sensor and connection of the electrical connection are required. Reconnect the negative pole of the battery and turn on the engine to complete the process. The OBD2 scanner should be used to reset the error code, and the goal is that it will not recur.
O2 Oxygen Sensor Replacement Cost
The typical cost of replacing the O2 oxygen sensor is around $250, with the sensor itself costing approximately $117 and the labor cost amounting to approximately $150. Prices may differ based on the type and brand of the car.
Should I Repair the P0132 Trouble Code Right Away?

OBD-II Trouble Code: P0132 Oxygen Sensor Circuit High Voltage (Bank1, Sensor1)
High Voltage Oxygen Sensor Circuit O2 Oxygen Sensor Circuit (Bank1, Sensor1)
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. This is due to the front oxygen sensor on Bank 1 malfunctioning. This code indicates that the temperature of the heated oxygen sensor is too high. Specifically, in the case of Ford automobiles, this signifies a voltage at the sensor more than 1.5 volts.
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. The front oxygen sensor on Bank 1 is involved in this.
Getting this error message means that you have a high reading from the heated oxygen sensor. That implies that the voltage at the sensor is more than 1.5 volts in the case of Ford automobiles. It’s possible that other cars are comparable to this model.
It is possible that a code P0132 indicates that one or more of the following has occurred:
- The heater circuit for the oxygen sensor is shorted out
- The sensor’s wire has been damaged or frayed (this is less common)
The most straightforward solution is to reset the code and see whether the problem persists. If the error code is returned, the fault is most likely with the frontBank 1oxygen sensor (Figure 1). You will very certainly end up replacing it, but you should also think about the following alternatives:
- Check for electrical issues (shorted or frayed wires, for example)
- Check the oxygen sensor’s voltage for proper operation.
Related DTC Discussions
- Verify that there are no electrical issues (such as shorted or frayed wires). Ensure that the oxygen sensor’s voltage is within specifications.

P0132: O2 Sensor Circuit High Voltage Bank 1 Sensor 1
P0132 is described as the O2 sensor circuit high voltage bank1 sensor1 in the O2 sensor circuit high voltage bank1. It is an error code that indicates that there is a problem with the oxygen sensor circuit. It is an indicator that the sensor has lagged or taken an excessive amount of time to flip from high to low (functioning) voltage for an excessive amount of time. It is critical for car owners to understand the significance of the p0132 code since a defective cylinder might result in a significant increase in fuel consumption.
- Engine that runs rough – This is the most visible indicator since the car does not operate smoothly whether it is both running and idle
- The p0132 error code may not be considered a serious problem, but it does have the effect of decreasing a vehicle’s fuel economy, as follows: Check Engine light illuminates – When this light illuminates, it is a clear indicator that there is a problem with the engine’s operation that has to be addressed.
- Extremely high fuel temperature
- Wires that are exposed and damaged
- The occurrence of a short circuit in bank 1 sensor 1
- Malfunction of the PCM. PCM software that is out of date
- The transducer for the engine’s fuel temperature is not functioning properly.
What to Check
The following are the actions that must be done in order to determine the source of the mistake.
- The dual trace lab scope is used to diagnose the p0132 code fault as the initial stage in the diagnostic process. In this approach, a time division graticule with time intervals of 100 milliseconds and a voltage of around 2V is used. The signal wires are then probed while the car is operating to determine whether or not the voltage remains constant at 900 mV and, if so, for how long. Lean (below 300mV) and rich (over 300mV) are the two operating modes of the oxygen cylinder (above 750 mV). Within 100 milliseconds, a well functioning cylinder should transition from lean to rich
- Range test. This exam is performed in the same session as the time test. The engine is operated at high speeds, preferably above 1500 RPM, with the throttle being closed and opened fast between each revolution. If the cylinder is in proper operating order, the transducer signal should rapidly transition from one voltage level to another within 100 milliseconds. Physical inspections should be performed as well. This procedure entails removing the cylinder and inspecting the sensor for the presence of a white coloration on the sensor surface. The presence of this white material indicates that the spark plug is not functioning properly, and it must be replaced with a functioning one. In most cases, once a mistake has happened, it is recorded in the PCM (power control module). In order to determine whether or not there are error codes in the PCM, an OBD-11 scanner can be utilized. The condition of poor wiring, including damaged and exposed wires, should be examined.
How to Fix the Error
- It is possible to rectify the error by replacing damaged or exposed wires since short circuits that may form on the cylinders are prevented by doing so. It is necessary to replace a spark plug that has developed a white look with a healthy one. ensuring that the fuel cooling system is in proper operating order in order to avoid the fuel from overheating
P0132 is a diagnostic problem code. High Voltage O2 Sensor Circuit Design (Bank 1 Sensor 1) In the engine bank that has one cylinder, this sensor is situated PRIOR to the catalytic converter, which makes it easy to locate. It searches for a return voltage by sending a reference voltage (typically 5 volts) to the variable resistor in the oxygen sensor and measuring the resistance between the two. Once the sensor has reached operating temperature, the PCM anticipates seeing a changing voltage. P0132 is a fault code that is set by the PCM when it detects a consistent high.
What causes a P0132 trouble code ?
In this case, because the voltage is high, the oxygen sensor detects a consistent rich fuel situation in the exhaust stream. The oxygen sensor should be replaced, according to the majority of auto parts retailers. WRONG! Although it is possible that the sensor is faulty, this is the most improbable source of the issue code. The engine is receiving an excessive amount of fuel. High fuel pressure, which indicates a faulty fuel pressure regulator, a clogged fuel line, and leaking fuel injectors are the most likely causes of the problem.
Check for a defective mass air flow sensor (MAP) that is giving a vacuum value that is greater than the actual engine vacuum. To find out how to replace an oxygen sensor, go to this page. 2012 is a year of transition. Rick Muscoplat is a professional musician. Rick Muscoplat posted a blog entry on
P0132 – Heated oxygen sensor (HO2S)
|Trouble Code||Fault Location||Probable Cause|
|P0132||Heated oxygen sensor (HO2S) 1, bank 1 -high voltage||Wiring short to positive, H025, ECM|
We strongly advise you to Torque Pro is a software program that allows you to control the torque of a motor.
What Does Code P0132Mean?
To operate, the internal combustion engine ignites a hydrocarbon (HC) fuel and burns it in conjunction with oxygen (O2), generating enough energy to spin the engine. In a perfect situation, the exhaust stream would consist of of water (H2O), carbon dioxide (CO2), and unreacted nitrogen (N) (N2). Because of the variances in engine running, air and fuel temperature, fuel composition, and a variety of other parameters, exhaust chemistry might be less than optimum. It is possible that excessive cylinder temperatures will result in the creation of nitrogen oxides, for example (NO and NO2).
- Other factors can contribute to the formation of carbon monoxide (CO), ozone (O3), and PM10 and PM2.5 (particulate matter smaller than 10 microns and 2.5 microns in size, respectively) pollutants.
- This allows the ECM to fine-tune the AFR, valve timing and lift, spark timing, and other parameters.
- It does this by recombining harmful emissions into safer compounds after they have formed.
- The ECM monitors the performance of the TWC by comparing oxygen sensor values taken before and after the TWC.
- When operating in normal mode, the ECM raised and decreased FT, always aiming to zero in on 14.7:1 AFR and utilizing the AFR sensors to verify its success.
- If the TWC is operating properly, the temperature of the heated oxygen sensors (HO2S) will not change much at all.
- If the TWC is operating properly, the downstream HO2S should only show a little reaction.
- This ECM then sets a DTC (diagnostic problem code) that is relevant to TWC function.
- To do so, it examines the heater and signal circuits to ensure that the voltage and resistance are within acceptable limits.
It will activate the malfunction indication lamp (MIL) and record a diagnostic trouble code (DTC) in system memory if the ECM detects a signal voltage that is greater or lower than the maximum or minimum value.

For reference, Bank 1 and Bank 2 refer to whether bank of cylinders is on the left or right side of the V arrangement, with Bank 1 having Cylinder 1 and Bank 2 carrying Cylinder 2. Inline engines may be separated into Banks, with Bank 1 being Cylinder 12 or cylinders 1 – 3 of the engine. Sensor 1 or Sensor 2 refers to the location of the sensor before to or after the TWC, respectively. Sensor 1 is located before to the TWC, while Sensor 2 is located following the TWC.
What are the common causes of code P0132?
DTC P0132 can be caused by a variety of factors that vary according on the year, manufacture, and model. Here are a few of the most often encountered.
- HO2S Defect – The most prevalent type of failure is caused by a fault in the sensor. HO2S has an average lifespan of fewer than 5 years due to the fact that it is constantly exposed to the environment as well as the heat from exhaust. In addition to being physically damaged by impact or road debris because they are exposed to the weather, cable harnesses, connections, and the sensor itself may be physically damaged as well. Water intrusion and corrosion are two typical problems.
What are the symptoms of code P0132?
The fact that the HO2S have absolutely nothing to do with fuel trim and are only used to verify TWC function is important to remember; however, FT problems, such as those caused by low fuel pressure or misfiring cylinders, could cause HO2S readings to be skewed, and possibly even set TWC or HO2S DTCs, but these would not result in circuit DTCs. Because the TWC is not necessary to engine operation, but rather serves as an emissions-control mechanism, you will not notice anything other than the MIL for the most of the time.
How do you troubleshoot code P0132?
It is important to remember that the HO2S have absolutely nothing to do with fuel trim and are only used to verify TWC function. FT problems, such as those caused by low fuel pressure or misfiring cylinders, could skew HO2S readings and possibly even set TWC or HO2S DTCs, but these would not result in circuit DTCs, as they would with FT problems. In most cases, you will not notice anything other than the MIL because the TWC is not crucial to engine operation and is only an emissions-control device.

Because the TWC is not crucial to engine operation, but rather serves as an emissions-control mechanism, you will not notice anything other than the MIL the vast majority of the time.
- Make required repairs if you discover an excessive amount of resistance or a short circuit. If the resistance is correct, the sensor should be replaced.
- Most people just replace the sensor when this happens, but you shouldn’t dismiss the sensor until you’ve eliminated the possibility of circuit failure.
- Internal resistance of the HO2S should be checked. The resistance measured from the heater positive to both sides of the sensor circuit should be greater than 10 k. If not, replace the sensor
- If you have access to live data from the HO2S and AFR sensors, you may compare the two values. If the HO2S is stuck low or high, it is fair to infer that the sensor is defective. If you have active testing, that’s even better since you may try to force a HO2S reaction to occur. If you receive no answer, you should consider a sensor or circuit malfunction.

Part 1 -How to Test Trouble Code P0132 (Dodge 3.9L, 5.2L, 5.9L)
It is not difficult to determine the root cause of the aP0132 O2 Sensor Circuit High Voltage (Bank 1 Sensor 1) problem. As part of this lesson, I’m going to walk you through some of the fundamentals of what DTC P0132 signifies, as well as how to do a step-by-step test of the downstream oxygen sensor. Despite the fact that this lesson is aimed at a 3.9L, 5.2L, or 5.9L Dodge/Jeep pickup truck, van, or SUV, the information and test may be applied to any 1996-2003 make or model.
P0132Basics You Need To Know
Take a look at some of the fundamentals of issue code P0132 to get you started on your journey. One of the most crucial things we need to understand is that this code is related to the performance of the oxygen sensor located upstream of the engine. The specifications are as follows: LOCATION: There are various names for this oxygen sensor, which is situated before the catalytic converter and is used in a variety of applications. The most often encountered are as follows:
- Oxygen sensors upstream
- Oxygen sensors before to the catalytic converter
- Oxygen sensors in front
The upstream oxygen sensors in your Dodge/Jeep car may be one or two in number depending on the model. Here are some more details to assist you in your search for the proper oxygen sensor:
- When there are two upstream oxygen sensors in a vehicle, a P0132 DTC is generated to identify the one that is on Bank 1. Engines with cylinders 1, 3, 5, and 7 (5.2L and 5.9L V-8 engines) as well as engines with cylinders 1, 3, and 5 (3.9L V-6 engines) are referred to as Bank 1. When there is just one upstream oxygen sensor before the catalytic converter, a P0132 DTC is generated, which identifies the only one that is present.
A P0132 DTC is shown on vehicles that have two upstream oxygen sensors, with the one on Bank 1 being identified by the DTC. Engines with cylinders 1, 3, 5, and 7 (5.2L and 5.9L V-8 engines), as well as engines with cylinders 1, 3, and 5 (3.9L V-6 engines), are classified as Bank 1. When there is just one upstream oxygen sensor before the catalytic converter, a P0132 DTC is generated, which identifies the only one that is present before the catalytic converter.
- The upstream oxygen sensor, which is placed before the catalytic converter, is creating and reporting an extremely high voltage to the PCM, which is causing the PCM to malfunction (Powertrain Control Module). Approximately 0.5 Volts (500 millivolts) will be present in this constant voltage. In fact, the PCM has been seeing this high voltage value for more than 2 minutes. In most cases, this constant high voltage is roughly 0.9 Volts DC (900 millivolts), however it can be anywhere between 0.5 and 1 Volt (500 to 1000 millivolts). Generally speaking, any continuous voltage greater than 0.5 Volts indicates a Rich situation
- However, this is not always the case, since the O2 sensor might fail and generate the same result (despite the fact that a Rich condition does not actually exist)
- The term ‘Rich condition’ simply refers to the fact that an excessive amount of gasoline is being pumped into the engine
- In other words, the engine is running rich.
The front (upstream) oxygen sensors will create a voltage that will continually and rapidly shift between 0.1 Volts DC and 0.9 Volts DC while the engine is running normally. As a result, when a P0132 causes the check engine light (CEL) to illuminate, the PCM is sensing a voltage that remains constant somewhere over 0.5 Volts for more than 2 minutes, indicating a problem. CAUSES THAT MAY BE INVOLVED: A P0132 diagnostic problem code can be caused by a variety of factors. The following are the most often seen reasons of a P0132 DTC:
- There are several possible causes of a P0132 DTC, the most frequent of which is a malfunctioning oxygen sensor that causes the sensor to become stuck and produce a continuous voltage greater than 0.5 Volts (500 millivolts).
- Fuel pressure is is too high
- Fuel injectors that leak
- Incorrect fuel pressure regulator (this jerk is a component of the fuel pump system on Dodge/Jeep automobiles, which is the subject of this instructional)
- Fuel is seeping into the intake manifold from the EVAP canister vacuum hose. A throttle position sensor (TPS) that is occasionally malfunctioning
- Because of a fault in the O2 sensor’s wiring, the PCM is not receiving the right signal.
- Typically, this is the consequence of the O2 sensor’s wiring or the engine wiring harness coming into touch with the exhaust pipe, exhaust manifold, or a hard edge (typically on the engine) and causing the insulation to melt on the wires.

P0132 Code – What Does It Mean & How To Fix It
This is one of the most often encountered OBD2 error codes. Read the rest of this article to find out what it means, how to solve it, and what additional codes may appear that are associated with it.
DTC P0132 is one of numerous OBD-II diagnostic trouble codes that may be set if the Oxygen (O2) sensor is not functioning properly. It can be set by the driver to indicate a problem with the sensor’s performance. This general fault code indicates that the Bank 1 Sensor 1 of the Oxygen sensor circuit is operating at a higher temperature than specified. A circumstance in which the Powertrain Control Module (PCM) determines that the heated Oxygen sensor voltage in your car has above the manufacturer’s predetermined temperature is known as a ‘hot sensor voltage exceedance.’ When the oxygen sensor temperature persists over 450 millivolts for more than 20 seconds, this is most commonly observed.
This information is required in order to maintain optimal engine performance while also limiting environmental damage to a very bare minimum.
For the most part, technicians do not consider this error code to be very significant.
That does not imply that this code should be ignored or ignored any longer.
There are a lot of issues that might cause the voltage of the bank 1 sensor 1 of your vehicle’s oxygen sensor circuit to spike to an extremely high level. The fact that these characteristics might differ from one car manufacturer to another is also very crucial for you to know about. But, regardless of the car’s make or model, we have created a list of the most prevalent reasons for this problem to occur in a vehicle. These are some of the reasons:
- In your vehicle’s O2 sensor circuit, there are several faults that might cause the voltage of the bank 1 sensor 1 to be extremely high. In addition, it is crucial to remember that these characteristics may differ from one car manufacturer to the next. But, regardless of the vehicle’s make or model, we have collected a list of the most typical reasons for this problem in vehicles. Included among these factors are
There are a variety of issues that might cause the bank 1 sensor 1 of your vehicle’s O2 sensor circuit to have an abnormally high voltage. It is also crucial to note that these considerations may differ from one car manufacturer to another. But, regardless of the car’s make or model, we have developed a list of the most prevalent reasons for this problem in a vehicle. The following are some of the reasons:
- The CEL is illuminated
- The vehicle’s fuel efficiency is poor. Engine performance that is reduced or unpredictable
- Along with the exhaust fumes, there is a plume of black smoke. Running in a rough manner
The diagnostic trouble code P0132 can be triggered by a variety of issues in a vehicle, ranging from a malfunctioning oxygen sensor to a faulty mass airflow (MAF) sensor, among others.
It is necessary to use an OBD-II scanner to examine the freeze frame data in order to make a perfect diagnostic for this code. Despite the fact that this code appears to be somewhat non-serious, we do not advocate performing a DIY fix for this diagnostic if you have no prior expertise.
- To achieve this, you’ll need to use an OBD-II scanner to download and retrieve the frozen frame data as well as any codes that have been saved by the PCM. The P0132 issue may be cleared by resetting all stored codes, which will also turn off the check engine light. Test driving the car once you’ve successfully reset the codes to see whether the code reappears. The most common cause of a return of the code is a problem with bank 1 of the oxygen sensor. Ideally, you should consider replacing it in this situation
- Utilizing the OBD-II scanner, you may examine real-time data and monitor the voltage levels that are being sent to the oxygen sensor. This procedure is carried out in order to guarantee that the sensor’s voltage is within acceptable limits. To finish, visually inspect the O2 sensor wiring, looking for frayed or exposed wires, as well as any damaged or frayed wires. Make any necessary repairs to the wiring.
Common Mistakes in Diagnosis:
When dealing with this error number, there are certain frequent mistakes that are made that need to be avoided. First and foremost, it is critical to thoroughly investigate the root of the problem before proceeding with the repair. It is possible that you will be required to replace the oxygen sensor as well as the air-fuel ratio sensor in order to remedy this problem and remove the fault code in your vehicle. Another possibility is that the MAF sensor has a problem and has to be replaced entirely.
If any of these conditions exist, the sensor must be replaced.
How Serious if P0132?
In general, technicians do not consider DTC P0132 to be a critical fault code to be shown on the computer. This is due to the fact that, other from higher fuel consumption, this code rarely poses a substantial danger to the vehicle’s drivability. While this is happening, a vehicle with this issue code is detrimental to the environment since it often produces dangerous chemicals into the atmosphere, such as hydrocarbons and nitrogen oxide.
What Repair Can Fix P0132?
In addition to the diagnostic procedures outlined above, it is possible that your vehicle will require further repairs in order to fully clear the code. The following fixes to your car should be considered in this situation:
- Replace the oxygen sensor if necessary. Replace the MAF sensor if it is necessary. It is necessary to troubleshoot the fuel pressure valve
- Also, the engine coolant temperature sensor should be replaced. Identify and repair any wire connections that are damaged, frayed, or exposed
- If you observe a buildup of white particles on the spark plug, you should replace it. Final step: repair or replace the PCM if the unit is faulty.
This diagnostic code is connected to other issue codes that deal with the malfunctioning of the O2 sensor circuit, particularly the bank 1 sensors, and is shown in conjunction with them. Some of these linked codes are as follows:
- The P0130 and P0131 codes indicate a malfunction in the O2 Sensor Circuit (Bank 1 Sensor 1). The P0133 and P0134 codes indicate a slow response in the O2 Sensor Circuit (Bank 1 Sensor 1). The code P0137 indicates a low voltage in the O2 Sensor Circuit (Bank 1 Sensor 2). The code P0038 indicates a high temperature in the Heated Oxygen Sensor Heater Control Circuit (Bank 1 Sensor 2). The code P0144 indicates a high voltage in the
At first glance, DTC Issue P0132 does not appear to be a very dangerous code. However, waiting too long before taking action against the code might exacerbate its consequences. Despite the fact that this is not one of the more well-known fault codes, DIY repair is not suggested for those who have no prior knowledge with it. In addition to the fact that your inexperience may cause the situation to get more complicated, you may also risk losing your manufacturer’s guarantee. As a result, having a professional do this repair is always the best option because it saves you valuable time while also posing less risk.

Dodge Ram P0132: Oxygen Sensor High Voltage (Bank 1 -Sensor 1)
Among the many different types of automobiles, the Dodge Ram is one that frequently displays the P0132 OBDII code. When the following conditions are met, the code is activated:
- For at least 20 seconds, the voltage at the sensor remains over the threshold value. The air fuel sensor remains in the rich biased mode for an excessive amount of time.
P0132 can also be caused by a number of less common issues. Here are some examples. We’ll go over them in more detail below. When the Ram’s O2 sensor voltage at B1S1 falls below a certain threshold, P0131 is triggered.
Dodge Ram P0132 Symptoms
Typically, the sole symptom of P0132 is the service engine soon light, which indicates that the problem is imminent. In certain circumstances, there may be additional signs and symptoms as well. These are some of the signs and symptoms:
- Engine has a rough idle
- The exhaust smells
- The service light is illuminated
- The MPG is poor.
Engine has a rough idle; exhaust smells; service light is illuminated; fuel economy is poor.
Dodge Ram P0132 Causes
The following are the most often seen problems that result in the P0132 code in the Dodge Ram.
They are provided in a sort of descending sequence from most to least likely to be the source of the problem.
- One of the most common reasons that P0132 is activating your service engine soon light is a faulty oxygen sensor (O2) in your vehicle. Although it may be tempting to replace it straight immediately, it would behoove you to first inspect the wire harness that surrounds it. See the section just below. They are reasonably priced at places like Autozone or Amazon. Problems with Wiring Harnesses – The cable that connects the front and rear oxygen sensors is extremely prone to failure due to corrosion. Due to the fact that O2 sensors are located under the chassis, they are prone to damage from road debris as well as a great deal of exhaust heat, this is the case. In particular, the downstream sensor is vulnerable to this phenomenon. On YouTube, you may learn how to locate a short in a wire harness. Deterioration of the Terminal – The terminal (the socket) to which the oxygen sensor is connected is likewise a rather vulnerable component to damage. You’ll want to double-check that there’s electricity flowing to the device. More information about this may be found straight below
- Incorrect O2 Sensor – In the event that you are receiving P0132 after having recently changed your Oxygen sensor, it is possible that the replacement was incorrect or defective.
Ram P0132 Diagnosis
Listed below is a wonderful video that goes over every facet of troubleshooting the P0132 error code: With the aid of a multimeter, it is easy to diagnose the P0132. If you use the multimeter, you’ll be able to see whether or not the voltage coming to and from the oxygen sensor is within specification. This may help you decide whether or not the problem is with your Ram’s O2 sensor or its wiring harness. Unless you happen to be in possession of a multimeter, it would behoove you to examine the wire that connects to the fuse box and the oxygen sensor first.
Additionally, a voltage test light may be used to detect whether or not the oxygen sensor is receiving any voltage at all (these are available for approximately $5 at Walmart).
Whenever the light illuminates, even for a fraction of a second, you know that you have a short circuit, which is causing the P0132 issue code to appear.
