Code P2433 Audi Description
The P2433 code for Audi vehicles indicates an issue with the Secondary Air Injection System Air Flow/Pressure Bank 1 Sensor Circuit being too high. The secondary air injection system is responsible for reducing harmful emissions by introducing fresh air into the exhaust system during cold starts. This helps to heat up the catalytic converter quickly and improve its efficiency in reducing pollutants. The sensor circuit in question monitors the air flow and pressure within the system and sends this data to the engine control module (ECM).
