Are you looking for the diagnostic procedure of the P2435 error code? Then keep reading further as you are at the right place. The failure of the PCM is generally known as the secondary air injection system air flow/pressure sensor circuit bank 2. Fresh air is sent by the secondary air injection system into the exhaust system during cold engine startup. This extra air helps in burning the exhaust emission that is formed during engine warm up. The functioning of the AIR system is monitored by the PCM with the help of an AIR pressure sensor. An improper signal by the AIR pressure sensor will make the P2435 error to get stored. In a few vehicles, the pressure sensor forms a part of the AIR control solenoid.

To lessen the emission of injurious pollutant which is sent into the atmosphere is the main function of the secondary air injection system. Fresh air is sent into the exhaust system through the secondary air injection system which in turn minimized the injurious pollutants which are released into the environment. The information about pressure and flow is collected by the secondary air injection system. It is further sent to the PCM through a voltage signal. If the signal of the voltage does not fall within the specification as determined by the manufacturer, then the P2435 error code will be stored by the PCM and the check engine light will turn on.

What causes this problem with the Secondary Air Injection System Air Flow/Pressure Sensor Circuit Bank 2?

• One-way check valve might be faulty.
• The air injection valve might be broken.
• Malfunctioning injection pump.
• Pressure sensor might be damaged.
• Burnt, shorted or dented pressure sensor wire
• Faulty or worn out pressure sensor connector.
• Dented pins of the pressure sensor connector.
• The vacuum switching valve might be defective.
• The electrical wires of the vacuum switching valve might turn out to be faulty, shorted or eroded.
• Cracked or imperfect vacuum switching connector.
• The pins of the vacuum switching connector might be dented.

1. Secondary Air Injection Pump - More amount of moisture can cause the failure of the secondary air injection valve. Replace or repair it as soon as possible.
2. Air Pressure Sensor - Your vehicle might start consuming more fuel if the air pressure sensor is defective. Fix it as soon as possible to avoid the P2435 error code.
3. Vacuum Switching Valve - Why not replace your defective vacuum switching valve with a best one from Parts Avatar when you can get at it at an affordable cost?
4. Powertrain Control Module - Overheating of the PCM can likely damage your PCM. Change it quickly by getting a new PCM from PartsAvatar.
5. Air Injection Valve - It is easy to get rid of the P2435 error code when the faulty or broken air injection valve is replaced as soon as possible.

If you are facing OBD error code P2435, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• When the engine is at rest, it might stall.
• The secondary air injection system might be loud.
• The check engine light will remain on.
• As you start the vehicle, the engine might stall.
• The hesitation of the engine during acceleration.
• P2435 error code might get stored in the PCM.

It is very important to fix the fault code P2435. So here are some ways with which you can correct this issue:

• The damaged one-way check valve needs to be changed.
• The defective air injection valve needs replacement.
• The air injection pump has to be fixed.
• The faulty pressure sensor needs to be altered.
• The pressure sensor wires that are broken, frayed or shorted have to be changed.
• The eroded or faulty pressure sensor connector has to be made alright.
• The pins of the vacuum switching connector which are bent have to be corrected.
• The broken switching valve needs fixation.
• The vacuum switching connector which is damaged, burnt or shorted has to be fixed.
• Replacing the corroded or molten vacuum switching connector.
• Fixing the bent pins in the vacuum switching connector.

To do all this, you will need few high-quality auto parts such as secondary air injection pump, air pressure sensor, the vacuum switching valve, powertrain control module, air injection valve and so on. From where will you get them? From your local store? Well, why go there when you can order quality parts with us while sitting in the comfort of your home. So, just browse through our website and order your needed parts today.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Clear every diagnostic trouble code in the order they appear in the PCM.
• With the help of a scanner gather every trouble codes which has been stored by the PCM and as well as the freeze frame data.
• Check the vacuum switching valve if they are frayed, broken or shorted and repair or replace them as needed.
• The vacuum switching valve connector must be checked for defects, erosion and bent pin and repair or change them as required.
• Every of the diagnostic trouble code from the PCM must be cleared. Monitor or perform a test drive to see if the P2345 error code appears again.
• Check the pressure sensor wire if they are frayed, broken or shorted and repair or replace them as needed.
• The pressure sensor connector must be checked for defects, erosion and bent pin and repair or change them as required.
• Every of the diagnostic trouble code from the PCM must be cleared. Monitor or perform a test drive to see if the P2345 error code appears again.
• Make sure that the one-way check valve is functioning properly.
• Repair or replace the one-way check valve if it is faulty.
• Every of the diagnostic trouble code from the PCM must be cleared. Monitor or perform a test drive to see if the P2345 error code appears again.
• Make sure that the air injection pump is functioning properly.
• The injection pump must be check for breaks or free connections.
• If you find any broken or loose connection in the hose of the air injection pump, it must be changed or fixed as needed.
• Check for fuses in the air injection system.
• Change or fix the defective wires or pumps which causes a blown fuse.

Common Mistakes When Diagnosing the P2435 Code

The general misdiagnosis of a P2435 error code is failing to add a drain tube when changing the secondary air injection pump. If it is important to change the secondary air injection pump, then it is essential to add a drain tube to the pump housing. Multiple failures can arise if you miss adding a drain tube to the secondary air injection pump housing. Before completing the diagnosis, it is essential to verify the one-way check valves as the failure of the one-way check valve is the common error which is linked with the P2345 error code.
