What causes a secondary air injection system malfunction?
CAUSES OF A FAILURE: CAUSE OF FAILURE Faulty ground and voltage supply can also cause the pump to fail. Blocked or leaking lines can also cause the failure or malfunction of the control or combination valve, resulting in the failure of the secondary air system.
What does a bad air pump sound like?
A bad air pump can make a howling noise. You should hear a faint vacuum-cleaner sound for about 30 seconds as your air pump operates. The lack of this noise can indicate that the pump is not working.
P0410 – Secondary Air Injection System Malfunction
The Secondary Air Injection System Malfunction error code P0410 is described as follows: This indicates that there is a problem with the vehicle’s emission control system, which can be caused by either an electrical or mechanical malfunction.
The error code P0410 indicates that there is a problem with the emissions system, which is most often caused by a faulty air pump. The air pump’s function is to circulate air through the exhaust system in order to reduce emissions. It draws in air from the outside and pushes it through one-way check valves to each bank of the exhaust system’s exhaust system. If any of the air pipes leading to the combustion valve are broken or lodged after changing the spark plug, this code is likely to be shown.
This code is activated 90 percent of the time when a one-way check valve has been broken or has enabled water (which naturally occurs in the exhaust) to enter the pump and cause it to malfunction.
Obviously, if the PCM activates the pump, the pump will not turn, resulting in an overload of the circuit and the ‘popping’ of the fuse (see illustration).
- Check The engine light is illuminated
- When the engine is being accelerated, it stutters. The air pump is making a noticeable noise because it is jammed.
- Air pump check valve(s) that are faulty
- Faulty vacuum lines or air control solenoids
- A faulty Air Pump or an Air Pump Relay
- A restricted system or a system plugged with carbon
- Water that has collected and accumulated in the AIR pump
- A frozen or corroded AIR pump
- A blown AIR pump fuse as a result of freezing
- A corroded or frozen AIR pump fuse as a result of freezing
- A blown
How to Check
During the period in which this error code is set, the Powertrain Computer Module (PCM) does not observe a significant drop in the voltage of the front oxygen sensor, where the air pump is expected to add outside air to the exhaust system and aid in the burning off of excessive HC and CO. As a result, it is critical to use the Scan Tool during a cold start in order to diagnose this error code. Some scan tools also allow technicians to check for SAS (Secondary Air Systems) while the vehicle is already warmed up, which is a convenient feature.
After 5 to 10 seconds, you should be able to hear the secondary air pump begin to operate – it makes a vacuum cleaner-like sound as it runs under the hood of the vehicle.
If this code does not appear, then that’s a tell-tale sign for a fault condition in the SAS.
If you hear the air pump motor start– Check the component that controls the air delivery, such as the Check Valve Solenoid, Check Valve, as well as the rubber shoes, passages and metal piping.
How to Fix
It is crucial to note that there is a TBS (Technical Service Bulletin) available for a number of General Motors vehicles that may be used to verify and correct this issue. The air pump will need to be replaced, and a new secondary injection pipe will need to be installed, according to the TSB. Simply changing the air pump will not always fix the problem; in fact, it is possible that the problem will recur on a regular basis. In addition to repairing the air pump, it is necessary to clean the hoses and install a new one-way check valve throughout the process.
In certain circumstances, individuals end up drilling a small hole in the rubber cover of the pump to prevent water from gathering and to ensure that the pump is regularly draining.
Also, if your automobile has already passed the bumper-to-bumper warranty expiration date, check to see if the emission warranty is still in effect or not. It is possible to get rid of this error code by doing the following steps:
- Both the air pumps and the one-way check valve should be replaced. Make an attempt to clean the air pump and then test it. Another component that needs be changed is a one-way air check valve. Remove and replace the air pump’s intake hose
- It is necessary to replace the air pump’s fuse (which may be found under the hood)

OBD-II Trouble Code: P0410 Secondary Air Injection System Malfunction
Malfunction of the Secondary Air Injection System
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 P0410 error code is associated with the emissions system. The AIR pump circulates air through the exhaust system to reduce emissions. Intake air is drawn in from the outside and pumped via two one-way check valves into each bank of the exhaust system.
If you live in a chilly region, and especially if you live in a climate with significant humidity, this water may be even more excessive.
Because when the PCM instructs the pump to turn on, a frozen pump will be unable to turn, resulting in an overload of the circuit and ‘popping’ of the fuse.
Among the possible signs and symptoms are:
- MIL lighting, without a doubt
- When accelerating, there is a pause. Noise caused by a faulty or blocked AIR pump
One or more of the following events may have occurred when the code P0410 was generated:
- It is possible that water has accumulated in the AIR pump or the vent solenoid and has frozen or damaged the pump. Because of the freezing, the AIR pump fuse has blown.
Note: There is a technical service bulletin (TSB) for a number of General Motors vehicles that addresses this code. The TSB recommends that the AIR pump be replaced, as well as the installation of a new secondary injection pipe, to correct the problem. The Technical Service Bulletin may be obtained on this ACDelco website. As an added precaution, replacing the AIR pump alone may cause the problem to recur once again (and again). If you are replacing the pump, you should also clean up the hoses and replace the one-way check valve as part of the process.
Occasionally, individuals have made a small hole in the rubber cover of their pumps, allowing any excess water to run out through it.
If your vehicle has reached the end of its bumper-to-bumper warranty period, check to see if the emissions warranty is still in effect!
- It is necessary to replace the AIR pump as well as the one-way check valve
- Additionally, inspect and replace the one-way air check valve after testing and cleaning the AIR pump. Replace the intake hose of the AIR pump. In this case, replace the AIR pump fuse (located under the hood).

Secondary air injection pump trouble code
An air injection reaction system is what is referred to as secondary air (AIR). Its purpose is to minimize emissions when the engine is first started from a cold start. Air pump (similar to a miniature compressor), a one-way valve, and a solenoid valve make up the system’s components. In order to complete the combustion process during a cold start, this pump is designed to feed air straight into the exhaust manifold from the intake system. When the computer is first turned on, it requests a rich combination.
- Because of this, the AIR pump is only activated for the first 20-120 seconds of engine running, or until the catalytic converter has reached operating temperature.
- Air one-way valve with solenoid for secondary air flow The PCM keeps track of the efficiency of the AIR pump by monitoring the O2 sensor’s readings.
- The PCM determines that it is cold by examining the engine coolant temperature sensor.
- The PCM supplies power to the AIR pump relay, which switches on the pump (electric pump draws high current, so it needs a relay to switch the power).
- If the O2 sensor does not indicate a lean situation within the specified time frame, the computer concludes that the pump is not operating properly and generates a P0411 secondary air injection system flow (low flow or no flow) failure.
- If the PCM detects a defect on the control coil side of the AIR relay, it sets a P0412 secondary AIR circuit malfunction on the AIR relay’s control coil side of the circuit.
- Once the AIR relay has been enabled, the PCM checks the voltage on the power line to the AIR pump to ensure that it is not overloaded.

OBD-II Trouble Code P0410: Secondary Air Injection System Malfunction
Malfunction of the Secondary Air Injection System
Here is what a P0410 means, in simple terms
P0410 is a generic OBD-II trouble code. When the engine’s control computer (ECC) identifies a problem with the air injection system, the P0410 code is shown on the instrument panel. In order to deliver air to the engine exhaust as it leaves the exhaust manifold, an air injection system (AIS) is installed. Depending on the application, injection points may be located at the exhaust manifold, before the catalytic converter (CAT), or midway through the catalytic converter. Oxygen is introduced into the exhaust stream to allow any residual fuel to continue burning.
A decision is made whether or not to activate the P0410 code based on data from the oxygen sensor(s) and/or when an electrical break occurs inside the air pump circuitry by the engine control module.
Whenever the ECC fails to detect a dip in O2 voltage, it generates a P0410.
Whatcaused my vehicle to set a P0410 trouble code?
The secondary air injection system is made up of a few different parts that work together. Begin with the most important component, which is the air compressor. It is possible for the air pump to be operated physically (through a serpentine belt) or electrically. The second component is the diverter valve, which is connected to the air pump’s outlet and regulates whether or not air is sent to the exhaust or to the surrounding atmosphere. The third component is the air injection system control solenoid, which is responsible for opening and closing the diverter valve.
The check valve is used to control air flow in only one direction, toward the exhaust and away from the pump.
It should be noted that some of these components can be merged into single units, like in the case of a check valve/diverter valve that is a single unit.
Among the most common P0410 triggering factors are:
- Air injection pump motor failure
- Air injection pump motor blown fuse
- The air injection pump motor is not functioning properly. Locate the fuses in the panel. Identify the air injection pump fuse and check the condition of the fuse
- The air injection tube is obstructed due to a constraint. It is possible that excessive carbon build-up has impeded air passage. The diverter valve for the air injection system is malfunctioning. Diverter valves are known to malfunction on a regular basis. The diverter valve is continually subjected to extremely high temperatures. The solenoid for the air diverter valve is faulty. Except if your vehicle is fitted with a vacuum operated diverter valve, this issue should also result in a P0491 code being displayed. A clogged catalytic converter increases back pressure in the exhaust system, preventing proper air flow downstream of the exhaust manifold and resulting in engine failure. This type of problem, which results in a P0410, is extremely unusual. The failure of the CAT will result in the occurrence of one or more additional catalytic converter-related fault codes. Sensor(s) for oxygen failure but not yet entirely defunct or faulty Slow switch rate of the oxygen sensor
What symptoms will my vehicle experience when trouble code P0410 is set?
- Your vehicle’s check engine light (CEL), Malfunction Indicator Lamp (MIL), or Service Engine Light (SEL) is illuminated when the engine is running. An lit light will soon appear, and freeze frame data will be recorded, containing information on the engine sensor data at the moment when the ECC identified the air injection issue. In addition, the trouble code P0410 will be stored in the ECC ROM memory. There should be no issues with driving maneuverability. Perhaps the fuel economy will suffer.
How can I fix a P0410 problem and where should I start?
A malfunctioning indicator lamp (MIL) or a service engine light (SER) on your car indicates that something is wrong with it. After a short time, a light will be flashed, and freeze frame data will be saved, containing information on engine sensor data collected during the time period during which the ECC identified an air injection problem. It is also possible that the trouble code P0410 will be stored in the ECC ROM memory. There should be no issues with driveability; nonetheless, Potentially reduced fuel efficiency.
- Check the functionality of the air pump
- Inspect the air pump fuse (if using an electric pump alone)
- Check the air injection pump relay (if using an electric pump). Check for any obstructions in the air injection tube. Ensure that the diverter valve is properly opening and shutting
- Check the diverter valve solenoid for appropriate operation, as well as the vacuum supply (if the diverter valve is vacuum operated). Check the check valve for the air injection system. Check to see if the door is stuck in the closed or open position. Excessive carbon deposit should be checked in the exhaust manifold and all air injection tubes. Check the switch speed of the oxygen sensor(s). Maintain the accuracy and responsiveness of the oxygen sensor(s) in terms of voltage production and response time to voltage increases and decreases.
Can I drive my vehicle with a P0410 trouble code and illuminated CEL?
- Despite the fact that you can drive your car while it has a P0410, bear in mind that your vehicle will not pass a smog check. Problems with the air injection system will not manifest themselves in terms of driveability. As long as a P0410 is registered in the ECC, the check engine light or malfunction indication bulb will be activated.
P0410 Code – Meaning, Symptoms, Causes (& How To Fix It)
Are you having trouble with the P0410 error code and are unable to remove it? Then you’ve come to the right article. You can find all of the information you need to get rid of the P0410 error code right here. Definition: P0410 – Secondary Air Injection System Not Working Properly
What Does the P0410 Code Mean?
Code P0410 indicates that a problem has occurred with the secondary air injection system, and that the problem is the result of either a mechanical or an electrical failure. The trouble code P0410 is generally shown when the vehicle’s emission system is malfunctioning or the air pump is malfunctioning. The primary function of the air pump is to supply air to the exhaust system in order to minimize the level of emissions. This pump sucks in fresh outside air before delivering it to specific banks in the exhaust system through a one-way check valve in the intake system.
When the P0410 issue code is activated, the following are some of the most typical symptoms you will experience:
- The check engine light comes on
- The engine hesitates when accelerating
- The check engine light comes on. Noises emanating from the air compressor
- The engine is operating at too high an RPM
- The fuel economy is reduced.
Possible P0410 Causes
The following are some of the most common reasons why the P0410 problem code is generated:
- Check valves on the air pump that have been damaged
- Bad pump relays
- Defective control solenoids Blocked air injection system
- Faulty O2 sensor
- Clogged catalyst
- And other issues. Fuel from the air pump has blown out
- Vacuum lines have been damaged.
Possible P0410 Solutions
- The air injection system should be repaired or replaced. The oxygen O2 sensor should be serviced or replaced. The air injection pump’s intake filter should be inspected and replaced. Repair a faulty wire connection
- Vacuum leaks should be repaired.
How to Diagnose the P0410 Code?
It is critical that you have the automobile battery charger on hand before attempting to diagnose the P0410 error code.
Troubleshooting this code needs the motor to be operating in order to look for variations in voltage and resistivity throughout the circuitry. This may result in a reduction in the battery’s charge as well as the generation of additional trouble codes.
Connect the OBD2 Scanner
It is critical that you have an OBD2 scanner on hand in order to diagnose the problem code P0410. Almost every vehicle built after 1996 is equipped with an onboard diagnostic system that keeps information about issue codes and allows the driver to diagnose and report problems. This scanner has the capability of reading the information recorded in the on-board diagnostic system (OBD2). The simple code reader, which just offers particular information about the code, or the sophisticated scanner (which also allows monitoring and recording of live data) are the two options for purchasing a code reader.
Visually Inspect the O2 Oxygen Sensor and Wiring Harness
Check your vehicle’s O2 oxygen sensor for signs of damage or corrosion by finding it and inspecting it. Additionally, inspect the wire harness for any loose connections. Poor connections, as well as filthy or contaminated O2 oxygen sensors, are frequently responsible for the generation of error code P0410.
Check the O2 Oxygen Sensor Voltage
The voltage at the O2 oxygen sensor should then be checked. Before testing, make sure the engine is completely cool and that the car hasn’t been driven for at least 10 hours prior to the test. Starting the engine and using a scanning instrument to detect the voltage at the oxygen sensor will yield the most accurate results. It is normal for the voltage to decrease below 125 millivolts (0.125 volts) after approximately 10 seconds, indicating that the secondary air system is operating properly.
Check for leakages
The air pump should be working when the voltage drops below 125 millivolts (0.125 volts). If the voltage does not drop below 0.125 volts but you can hear it running, carefully inspect all hoses, valves, and the solenoid for leaking.
How to Replace the Secondary Air Injection Pump
Even if you have tested everything else, including the O2 oxygen sensor and all electrical connections, it is conceivable that the secondary air injection pump is faulty and will need to be replaced. You have two options for replacing the part: either take it to a professional technician or do it yourself.
Socket Wrench Gloves Ratchet Safety Goggles Ratchet
Step 1: Locate the air injection pump
Locate the air injection pump under the hood of the car by opening the hood. In addition to being placed near the front of the engine, it is surrounded by the serpentine belt. Make sure there is a belt routing diagram under the hood of the automobile so you can figure out how to re-attach the serpentine belt once it has been removed.
Step 2: Remove the Serpentine Belt
Remove the serpentine belt from the pump using a ratchet and unhook any hoses that are connected to it.
Step 3: Remove electrical connections and bolts
Afterwards, disassemble the pump by removing all electrical connections and vacuum lines from it, as well as the screws that hold it together.
Step 4: Remove the Sensor
Remove the pump from its location with care and replace it with the new air injection pump.
Step 5: Installing the new air injection pump
Install the new pump and ensure that all electrical connections and hoses are properly connected. Check to see that the screws are correctly attached and that they are appropriately tightened.
Step 6: Attach the Serpentine Belt
Replacing the serpentine belt and closing the hood are the next steps.
Secondary Air Injection Pump Replacement Cost
The cost of replacing the air injection pump is between $300 and $400 on average, depending on the automobile type and brand being used. Workmanship costs around $100, while the component itself costs approximately $220 to $260.
Should I Repair the P0410 Trouble Code Right Away?
The trouble code P0410 does not create any significant changes in driving behavior, but it does result in a significant reduction in the vehicle’s fuel usage. In addition, your vehicle will begin to release harmful toxins into the environment. If the error code is ignored for an extended period of time, it is possible that the engine and exhaust system of the vehicle will be damaged.
Recommended Tools to Fix P0410 Code
Charger for automobile batteries To check voltage and resistance values, use a digital multimeter. To scan for issue codes, use an OBD2 scanner. Clean the sensor using an electric cleaner in order to service it.

What Does Code P0410Mean?
Fault code for the OBD II Some cars are equipped with a Secondary Air System, also known as the Secondary Air Injection System, which has a problem or defect. The code PO 410 relates to this issue or defect. While most engines run on highly enriched air/fuel mixtures during cold starts, the system is designed to inject atmospheric air into the exhaust system to aid in the oxidation, or burning off, of uncombusted and/or partially combusted hydrocarbon molecules in the exhaust stream that result from incomplete combustion during cold starts.
The simplified design of a typical Secondary Air System arrangement is seen in the figure to the right.
What are the common causes of code P0410?
Because Secondary Air systems are very straightforward, there are only a limited number of potential causes of system failure. The most prevalent reasons are as follows:
- Pump check valves that are defective or faulty
- Pump relays that are defective or faulty
- Control solenoids that are defective or faulty
- Hoses and ducting that have ruptured or are leaking
- Carbon buildup in hoses, ducting, and other components causes restrictions. Bad connections, inadequate ground connections, or short circuits caused by faulty wiring can cause power interruptions or disruptions in the power supply to the pump motor, among other things.
NOTE 1: Because air pumps are notorious to break without notice, it is easy to attribute system failure on a damaged pump when the true cause is frequently a faulty relay or other component. One of the most common misdiagnoses is when check valves are assumed to be functional even though they may be somewhat hindered by carbon, resulting in reduced airflow to the exhaust, which can cause the Check Engine light to illuminate. NOTE 2:Some General Motors models are susceptible to system failure owing to the intrusion of moisture into the pump and motor components.
You may get the applicable Technical Service Bulletin by clicking here. It should be noted that this TSB requires for the repair of several hoses and other components in addition to the replacement of the damaged motor/pump.
What are the symptoms of code P0410?
- In the majority of situations, the Check Engine light will illuminate
- However, on some cars of European origin, the Pollution Control warning light will glow. In a great number of situations, there will be no unfavorable symptoms or external signals of problem
- In other words, there will be no issue. In certain circumstances, the air pump may be noisy owing to mechanical wear or the presence of foreign items in the pump
- However, in most cases, the air pump is quiet. While the engine is cold, it is common for there to be some reluctance when using the accelerator. There will be a variation in the degree of hesitation from vehicle to vehicle, however the existence of code P0 410 shows that there is a particular reason of the hesitation, in this case a malfunction of the Secondary Air System
How do you troubleshoot code P0410?
It is possible that the absence of outside air to burn off excessive hydrocarbons in the exhaust system during a cold start causes the voltage across the front oxygen sensor to not decrease to a predefined threshold, which results in the setting of code P0410. It is necessary to employ appropriate diagnostic equipment for troubleshooting, with the ideal being acan tool that can monitor data streams; however, this feature is often not accessible on low-cost instruments. However, while certain sophisticated scan toolshave the capability of performing diagnostic checks on the Secondary Air System while the engine is running, this feature is not often present on scan tools that are available to DIY technicians, as previously stated.
After confirming that the data streams are being monitored by the scan tool, begin running the vehicle and checking that the voltage across the front oxygen sensor decreases to, or below, 125 millivolts (.125 Volts) after about 5-10 seconds.
Therefore, complete the following checks:
- If the voltage does not decrease below 125 millivolts but you still hear the air pump working, look for leaks in all of the hoses, ducting, valves, and solenoids that are connected to the air pump. Keep in mind to check for blockages such as carbon build-up in all hoses, ducting, and valves as well. if the air pump does not turn on, examine all of the associated fuses, relays, wiring, and the pump motor for continuity, and replace or repair as necessary
- It may be essential to remove the exhaust manifold(s) and/or cylinder head(s) in order to get access to the system ports for the purpose of clearing out carbon deposits if the problem persists despite these examinations.

- P0411 is triggered when there is insufficient airflow to the exhaust, which is often caused by constraints or leaks in the system. As contrast to the air pump and check valves, the control solenoid is the source of the code P0412, which is set when there is a problem with the solenoid. P0492 is activated when there is an inadequate flow of air on bank1, which is the side of the engine that contains cylinder1
- P0492 is activated when there is an insufficient flow of air on bank2, which is the side of the engine that includes cylinder2. When it comes to the engine, bank2 is best characterized as the side that does not contain cylinder1.
BAT Team Discussions for P0410
- Pickupcodes P0410 and P1404 on a 1998 GMC 1500 These are the codes that are programmed into my V8 Pickup from 1998. Do you have any suggestions? I replaced the EGR valve with a known-good one and will wait a little to see whether the errors are cleared. I do not have access to a scanner to clear the codes. The other error number, P0410, which indicates a problem with the secondary air injection system, is a mystery to me. Where can I get the secondary ai for a 2000 Saab 95 that will not start? I very recently purchased the vehicle, thus I am unaware of its previous ownership. The automobile died when the night panelbutton was pressed twice in succession on the dash. The engine goes over, but there is no fire. When I purchased the vehicle, the check engine light was illuminated. I used a scanner to read the codes, and there were two of them: P0410 and P1300. I did not remove them from my computer. The following day, this occurred: 2001 Saturn SL2 1.9 DOHC p0301p0410 codes were detected. In driving, the automobile has acquired a minor miss.rpm 750 in the transmission. p0301 misfire on cyl 1 of the engine. First and foremost, I’m going to replace the wires, plugs, and ignition coils. All of these were really replaced within 20,000 miles of each other recently. On the motorway, the automobile has a lot of power. It does not make any stumbling movements when accelerating. I have a question about the following: ’01 Aurora Codes PO 410 and 742′ The check engine light is your buddy
- Do not turn off the diagnostics system. It appears that you completed a clean and test drive. Is it possible for your scanner to read the P1xxx manufacturer specific-P18xx? – THIS IS IMPORTANT! I’ll email you additional information about the TCC later. P0742 The TCC is locked in the ON position due to hydraulic pressure. Take a look at the following items: 2008 Mercury Milan Diverter Valve In my 2008 Mercury Milan, the DTC codes P0410 and 0491 have been activated. According to what I’ve discovered, this is the path that leads to the secondary air diverter valve. This part does not appear to be available on the Auto Zone website. Is there an other name for this section?
Secondary Air Injection System Codes: Toyota & Lexus
Any breakdown of a component of the Secondary Air Injection System will often result in the check engine light (CEL) being illuminated and the Engine Control Module (ECM) storing fault codes. When you hear a loud vacuum cleaner noise for 20-30 seconds after starting your car from a cold start, you know your air pump is malfunctioning. The majority of these mechanical issues also force the car to enter ‘limp mode,’ which is a state in which throttle response is reduced to 50 percent in order to preserve the engine from further harm.
In order to properly install the Hewitt-Tech bypass module, we strongly advise that you fix any codes that are not linked to the Secondary Air Injection System.
The following are the most frequent SAIS fault codes, which may often be resolved by the Hewitt Tech bypass or in conjunction with a kit addition, unless otherwise specified. Please refer to the Bypass Kit Comparison Chart or the relevant product listing for code coverage confirmation.
Mechanical SIAS Fault Codes:
P1441– Switching Valve No. 2 is stuck in the open bank position. 1P1442– Switching Valve No.2 Is Stuck in the Close Bank Position. 1P1444– Switching Valve No.2 is stuck in the open bank position. Two-way switching valve No. 2 is stuck in the close bank position. Stopped Switching Valve on the Open Bank (P2440) 1P2441– Switching Valve Is Stuck in the Closed Bank Position 1P2442– Switching Valve Is Stuck in the Open Bank Position 2P2443– Switching Valve Is Stuck in the Closed Position 2P2445– Pump Stuck OFF Bank 1* Please check the red text below for an important cold weather remark.
Electrical SAIS Fault Codes:
No.2 Switching Valve Is Stuck Open Bank (P1441 ). One of the Switching Valve No.2’s is stuck in the close bank position. One of the switching valves, number two, is stuck in the open bank position. No.2 Switching Valve Stuck in Close Bank, 2P1445. Stopped Switching Valve on the Open Bank, 2P2440. 1P2441– Switching Valve Is Stuck in the Closed Bank Position. 1P2442– Switching Valve Is Stuck in the Open Position Stopped Switching Valve on a Closed Bank, 2P2443. The pump at 2P2445 has been stuck in the off-bank 1 position.
To guarantee that the Hewitt-Tech bypass module functions properly, it is necessary to resolve any exceptions, such as a blown air pump fuse or broken air pressure sensors, at the same time.
Pressure Sensor SAIS Fault Codes:
P2431– Air Flow / Pressure Sensor Circuit Range / Performance Bank (Air Flow / Pressure Sensor) The 1P2432 circuit is an air flow and pressure sensor circuit with a low bank. Circuit with an air flow and pressure sensor, 1P2433, is a high-bank configuration.

When an Air Switching Valve is open for a lengthy period of time, this is the most common source of the problem.
Compatibility with a compatible Pressure Sensor addition is necessary in order to clear
Explanations, Exceptions and Other Codes
This is the ‘Limp Mode’code, which indicates that your vehicle’s VSC, TRAC, and other safety systems have been disabled. Although not all scanners are capable of reading the C codes, they are almost certainly there if you are in ‘limp mode.’ Do not be concerned — when you install a Hewitt-Tech bypass kit to remove other issue codes, this code will be cleared as well.
P2445 – Pump Stuck OFF Bank 1
This code is typically generated when the secondary air injection pump is unable to provide adequate air pressure due to damage to the pump impeller or because the air pump motor has been damaged and/or the air pump fuse has blown. It is usual to find a P0418 code that indicates that the air pump motor has been damaged in addition to the P0418 code. It is possible that this code will appear if the air pump fuse has blown, however you may not see a P0418 code until the fuse has been replaced. If you only encounter the P2445 code while your vehicle is cold, the Hewitt-Tech bypass kit can help you clear the issue.
- If you start your car in subzero conditions and the P2445 code appears as you approach 50 mph, the problem is caused by a fault in the engine control module.
- Having a Hewitt-Tech bypass kit installed on your vehicle does not indicate that the item is defective; rather, it indicates that there is a programming error in the car’s ECM.
- The sole known cure for this cold weather bug is a computer re-flash, which was explained in a highly specific but no longer accessible limited service campaign by Toyota, which was launched in 2008.
- In response to the release of the service bulletin for codes P0418/P2445, which instructs service managers and techs to replace the whole system, this limited service campaign has ended or has been purposely removed from the system by the company.
- It is not possible to address the cold weather issue by replacing the complete system because there is no computer upgrade (re-flash) performed under this service bulletin.
- Utilizing a startup/warmup/shutdown/restart sequence, the first approach actively prevents the glitch from occurring.
- The first step in achieving this goal is to identify that the engine temperature is near or below freezing when the engine is initially started after it has been off for at least seven hours (cold start).
If you drive at 50 mph or greater under the freezing start condition, this will cause the engine start temperature to be freezing and, in a second drive cycle, will prevent the glitch from occurring when driving at this speed.
It should be noted that this warmup/shutdown/restart cycle would only be required if the temperature is at or below freezing and the vehicle has been idle for at least seven hours.
Many parts of the country seldom see temperatures below freezing or even below zero degrees Fahrenheit, or at least not for an extended period of time.
Once the bug has been resolved, it will not recur until the first drive cycle after the car has been idle for 7 hours or longer and you exceed 50 miles per hour during the initial cold start driving cycle.
There is still a chance that we will be able to discover a solution to the freezing temperature problem, but for the time being, these are the only two options we are aware of.
It is possible that you are experiencing this issue, however it will cease occurring once your starting temperatures are once again over freezing. If you have any questions concerning these processes, please contact us at 1-800-307-7671 (toll-free).
P011B – Temperature Correlation Error
This code is generated when the temperatures of the air intake and engine coolant do not fall within a specified range of each other during the correlation test on a cold start, resulting in an error. The most likely reason for this code to appear is when a Hewitt-Tech bypass kit from 2005-2007 is placed on a 2008 or newer car. In particular, the V5 and subsequent units are especially engineered to avoid this problem on vehicles manufactured after 2008.
P106B – Pressure Sensor Correlation / Evap. Pressure Sensor
When comparing the pressure of the surrounding atmosphere, three pressure sensors are employed. Two of them are located in the secondary air switching valves, while one is located in the evap pressure sensor. This code is shown when one of the three sensors does not read readings that are consistent with the other two sensors. Typically, P106B is generated by driving a vehicle while one of the air switching valves is left open, allowing exhaust or moisture to seep back into the pressure sensor for an extended length of time or over a long distance, resulting in a P106B code.
If the problematic sensor is a component of the SAIS, we provide Pressure Sensor Replacements (direct, wired, and plug-and-play) that may be added to the Hewitt-Tech bypass kit to resolve the issue without the need to replace the faulty air switching valve or other components.
As a result, the P106B code will remain visible even after you have installed the Hewitt-Tech bypass module and cleared the codes.
If you are submitting the form, please include your vehicle details as well as any error codes.

STRUCTURE OF THE ACTIVE SECONDARY AIR SYSTEM:STRUCTURE
(This page was last updated on September 28, 2020) This isn’t the first time someone has asked the question ‘what is a secondary air injection pump?’ In this post, we’ll go over the function of the secondary air pump, as well as the signs and symptoms to look for that suggest the pump is failing to function properly.
What Does a Secondary Air Pump Do?
The secondary air injection pump (also known as a smog pump or SAI pump) is responsible for reducing the amount of carbon dioxide emitted from a vehicle’s exhaust pipe after it has been stopped. This is important due to the fact that a vehicle engine will never be completely efficient throughout the combustion process. By injecting fresh air from outside into the vehicle’s exhaust stream, the pump can help to reduce carbon dioxide emissions. The pump is located after the exhaust manifold and prior to the vehicle’s catalytic converter.
This contributes to a safer environment by reducing the amount of air pollution that is released outdoors.
You will not be aware of this until you are subjected to an emissions test.
Both possibilities are not something you’ll want to happen to your family or friends.
Top 5 Bad Secondary Air Injection Pump Symptoms
Failure of the secondary air injection pump is straightforward to diagnose if you are aware of the signs and symptoms to look for. The following are the five most typical signs of a failed secondary air injection pump, as identified by the manufacturer. It’s likely that you’re dealing with a defective secondary air injection pump if at least two of the symptoms listed above appear, and you should have it repaired as soon as possible.
1) Check Engine Light
One of the first signs of a faulty secondary air injection pump is the appearance of the Check Engine warning light on the dashboard. When there is an issue with the secondary air injection pump, the engine control unit can immediately identify it. Because the air pump’s operation has an affect on the engine’s performance, any problems with it will result in the Check Engine warning light on the dashboard turning on. You will need to utilize a vehicle code reader to obtain any error codes that have been saved in order to determine the true reason of the check engine light.
2) Failed Emissions Test
The secondary air injection pump’s primary function is to limit the amount of hydrocarbons released by your emissions system. As a result, if you have a faulty secondary air injection pump, your emissions system will be enabling an excessive amount of hydrocarbons to be discharged into the surrounding environment. Not only does this signal doom for the environment, but it also bodes doom for everyone who has to submit to an emissions test in the future. Even if you do not reside in a state that mandates emissions testing, if your secondary air injection pump fails the test, your vehicle will be disqualified from driving on the road.
3) Weak Acceleration
Hydrocarbons in your emissions system are reduced by the use of a secondary air injection pump. As a result, if your secondary air injection pump is malfunctioning, your emissions system will be enabling an excessive amount of hydrocarbons to be discharged into the environment.
The result is not only bad news for the environment, but it also signals bad news for everyone who has to take an emissions test in the near future. It is possible that your secondary air injection pump will fail an emissions test if you reside in an area where such testing is required.
4) Engine Stalling
The engine in your car may stop or hesitate while you are driving regularly at first, and you may not even realize it. Inconsistent power gaps from the engine might be caused by a secondary air injection pump that is worn down. It is possible that the power is OK one minute and that the engine shuts down the next because the RPMs have dropped too far. A failure to replace the pump may result in the engine continuing to stall at the most inconvenient of times.
5) Low Idle
When your engine is idling, look at the tachometer to see what the current revolutions per minute (RPM) are. The usual rotational speed of an idling engine is between 600 and 1,000 revolutions per minute. However, if the secondary air injection pump is not functioning properly, the engine’s rotational speed would reduce significantly. As previously said, this may cause the vehicle to vibrate or possibly stall. If you’ve previously experienced engine stalling, sluggish acceleration, and the illumination of the check engine light, you should get the secondary air injection pump checked out as soon as possible.
