Code P0021 2009 Nissan Pathfinder Description

The P0021 diagnostic trouble code (DTC) for a 2009 Nissan Pathfinder indicates an issue with the Intake Valve Timing Control Performance on Bank 2. This code specifically relates to the intake camshaft on the side of the engine that contains cylinder number 2. The Intake Valve Timing Control (IVTC) system is responsible for adjusting the timing of the intake valves to optimize engine performance and fuel efficiency. When the ECM (Engine Control Module) detects that the actual performance of the IVTC system does not match the desired performance, it triggers the P0021 code.
