Code P0022 Mercedes-Benz Description

The P0022 code for Mercedes-Benz indicates that the 'A' camshaft position timing is over-retarded on bank 2. This means that the timing of the camshaft on the bank 2 side of the engine is not in sync with the expected position, causing a timing issue. The camshaft position sensor is responsible for monitoring the position of the camshaft and sending this information to the engine control module (ECM). When the ECM detects that the camshaft timing is over-retarded, it triggers the P0022 code and illuminates the check engine light.
