Audi DTC P2432 – Air control solenoid failure, Powertrain Control Module (PCM) failure, Secondary Air System pressure sensor failure, Wiring issue

DTC P2432 meaning on Audi

DTC P2432 refers to a fault in the Secondary Air Injection System, specifically indicating a failure in the air control solenoid. This system is designed to reduce emissions during cold starts by injecting air into the exhaust stream to help burn off excess hydrocarbons. The code suggests that the Powertrain Control Module (PCM) has detected an issue with the operation of the air control solenoid, which may affect the overall performance of the vehicle and its emissions output.
