What is code P2431?

secondary air system

If your car is showing the P2431 engine code, it means that your secondary air system, which pumps fresh air into the exhaust to reduce vehicle emissions, has a problem. An incorrect airflow has been detected, and you should get it fixed promptly to avoid a failed emissions test.

What causes a P0411 code?

Diagnostic trouble code (DTC) P0411 stands for “Secondary Air Injection Incorrect Flow Detected.” This code warns about a potential airflow issue in the secondary air system.

What causes P2440?

Typically, P2440 is tripped because the Bank #1 Pressure Sensor detects pulsation of exhaust gas despite ECM commanding the Air Switching Valve to close. Meaning the Switching Valve is Stuck Open.

What causes secondary air injection malfunction?

A faulty pump is generally the most frequent cause of the system failing. Ingress of moisture can cause damage which results in seizure of the pump. Faulty ground and voltage supply can also cause the pump to fail.

Can a bad O2 sensor cause a P0411 code?

What Does Code P0411 Mean? Diagnostic Fault Code P0411 is indicative of a general lack of flow from a vehicle’s secondary air injection circuit. In turn, this lack of airflow is registered by the affected vehicle’s O2 sensors and is recorded by the PCM/ECM as a diagnostic fault.

How do you fix a secondary air injection system malfunction?

What repairs can fix the P0410 code?

  2. Replacing O2 sensors that respond too slow as they age.
  3. Replacing the air injection pump intake filter clogged with debris.

Can you drive without secondary air pump?

Technically speaking, you can drive without a secondary injection pump. However, doing so is not advised. What is this? This stems from the fact that a faulty secondary injection pump can cause a host of drivability-related issues, most of which can vary significantly in severity, on a case-by-case basis.
