P2432 - OBD Trouble Code

<<See All OBD Codes

This error code is generally known as the secondary air injection system air flow/pressure sensor circuit low bank 1. The natural air from the outside is sent into the exhaust system during a cold startup of the engine by the secondary air injection system. The highly rich exhaust emission is burnt by this additional air which is formed as the engine keeps warming up. AIR pressure sensor is used by the engine computer to look after the operation of the AIR system. The error code, P2432 might get stored if the AIR pressure sensor sends an incorrect signal and in some vehicle, the pressure sensor comes as a part of the AIR control solenoid.

If the P2342 error appears in the vehicle, then the ECM has found an issue with the secondary air injection systems pressure sensor or air flow circuit. When the engine is cold, a part of the emission control that is the secondary injection system pushes air into the exhaust stream so that the process of warming up the catalytic converter speeds up.

Cylinder#1 is present in bank 1, and the P2432 error signifies that there is low air pressure to the secondary air injection system.

This error usually gets stored during cold condition. A one-way check valve is used by the injection pump for the secondary air injection system which has the air inlet hose for protection. If the one-way check valve is faulty, then the condensation will enter the pump and freeze. The circuit will be overloaded and there will be damages if ice is present in the pump. The wires and connectors can overheat and burn if the temperature of the engine exhaust is too high.

What causes this problem with the Secondary Air Injection System Air Flow/Pressure Sensor Circuit Low Bank 1?

• The one-way check valve might be damaged.
• Air injection pump might be faulty or broken.
• Broken or faulty air injection valve.
• Sensor wires might be poor or faulty.
• The vacuum switching valve might be broken or worn out.

1. Secondary Air Injection Pump - The secondary air injection pump can be defective if there are faulty grounds or voltage supply. Fix the error as soon as possible to avoid P2432 error code.
2. Air Pressure Sensor - Hesitation of the engine to start during acceleration is a sign of a damaged air pressure sensor. Get rid of it as soon as possible.
3. Catalytic Converter - If the exhaust valve is leaky, then the catalytic converter can turn out to be faulty. Get the best catalytic converter for your vehicle from PartsAvatar.
4. Air Injection Valve - The P2432 error can be avoided if the defective air injection valve is immediately fixed.
5. Vacuum Switching Valve - Is your vacuum switching valve damaged? Looking for the right replacement part? Parts Avatar has got everything you need.
6. Air Control Solenoid Valve - Flashing of the check engine light in the dashboard is a sign of defective air control solenoid valve. Fix it as quickly as possible.
7. Powertrain Control Module - One main reason for a damaged powertrain control module is because of voltage overload where the voltage will be more than expected and it will likely damage the powertrain control module. The damaged powertrain control module will need immediate replacement so that the P2432 error code can be avoided.

Willing to know some common symptoms of OBD Code P2432? Your wish is our demand. Have a look at them below:

Common Symptoms

• When the engine is idle, it might stall.
• Either the warning light or the check engine light will keep flashing.
• The engine might produce a very loud sound due to the noise which comes from the secondary air injection system.
• During startup, the engine might start stalling.

We have listed out so ways which would help you to correct the occurrence of OBD Code P2432. They are mentioned here as follows:

• The faulty air injection pump has to be fixed or replaced.
• The defective valves like air injection valve, switching, a one-way check valve must be fixed.
• The broken wires need to be fixed.
• Changing or altering the faulty pressure sensor.
• The damaged hoses or fuses need to be replaced.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety secondary air injection pump, air flow sensor, air pressure sensor, catalytic converter, air injection valve, vacuum switching valve, air control solenoid valve, PCM and many more. Now all your problems would vanish within no time.

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

• With the help of a scanner, check for the diagnostic trouble codes such as P2432 error code which is stored in the ECM.
• Carefully inspect for any possible damages and fix or change them as needed.
• Check for any possible damages in the wires and replace them as required.
• The air injection pump has to be made clean of moisture and tested.
• Check for possible damages or erosion from moisture in the pressure sensor and fix or alter them as needed.
• See if there are any possible damages in the air injection system such as the hoses or fuses for any defects and fix the issue as needed.
• Test drive the vehicle by clearing the error code and see if the error codes appear again.

Common Mistakes When Diagnosing the P2432 Code

One common mistake which is made during the diagnostic procedure of P2432 error is failing to check and the correct the damaged one-way check valve. Even a small mistake can result in multiple changes of the secondary air injection system and simultaneous pump failures.
