Code P0022 Lexus Description

The P0022 code for a Lexus indicates that the camshaft position 'A' timing is over-retarded on bank 2. This means that the timing of the camshaft in relation to the crankshaft is not within the specified parameters set by the manufacturer. The camshaft position sensor helps the engine control module (ECM) determine the correct timing for fuel injection and ignition. When the camshaft timing is over-retarded, it can lead to poor engine performance, reduced fuel efficiency, and potential damage to the engine if not addressed promptly.
