Code P0223 2002 Nissan Sentra Description

The P0223 diagnostic trouble code (DTC) for a 2002 Nissan Sentra indicates a problem with the Throttle Position Sensor/Switch 2 Circuit High Input. The throttle position sensor (TPS) is a crucial component of the vehicle's electronic control system, as it monitors the position of the throttle valve and sends signals to the engine control module (ECM) to adjust fuel delivery and ignition timing accordingly. In this case, the ECM has detected a high voltage input from the TPS, which can lead to a variety of performance issues.
