Code P0223 2005 Nissan Pathfinder Description

The P0223 diagnostic trouble code (DTC) for a 2005 Nissan Pathfinder relates to the Throttle Position Sensor/Switch 2 Circuit High Input. This code indicates that the engine control module (ECM) has detected a high voltage input signal from the throttle position sensor (TPS) or its circuit. The TPS is a crucial component that monitors the position of the throttle valve and sends this information to the ECM to adjust the air-fuel mixture for optimal engine performance.
