Code P0223 2003 Nissan Sentra Description

The P0223 diagnostic trouble code (DTC) for a 2003 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 fuel injection system, responsible for monitoring the position of the throttle valve and sending signals to the engine control module (ECM) to adjust fuel delivery and ignition timing accordingly. When the ECM detects a high input signal from the TPS, it triggers the P0223 code, indicating a potential issue with the sensor's circuit.
