P2431: When Your Car’s Secondary Air Injection System Goes Haywire

The P2431 code is related to the Secondary Air Injection (AIR) System. This system helps to reduce hydrocarbon exhaust emissions during a cold start-up.

The code indicates an issue with the AIR FlowPressure Sensor Circuit RangePerformance Bank.

The Powertrain Control Module activates the AIR system by supplying grounds to the AIR pump and the AIR valve relays. The AIR pump sends pressurized fresh air into the pipeshoses through the open controlshut-off valve, and into the exhaust manifold. The AIR system pressure sensor is used to monitor pressure at the AIR control solenoid valvepressure sensor assembly inlet during the commanded ONOFF states.
