Code P0222 2012 Nissan Pathfinder Description

The P0222 diagnostic trouble code (DTC) for a 2012 Nissan Pathfinder indicates a problem with the Throttle Position Sensor/Switch 2 Circuit, specifically a low input signal. The throttle position sensor (TPS) is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and ignition timing, optimizing engine performance and efficiency.
