Code P0223 2011 Nissan Altima Sedan Description

The P0223 diagnostic trouble code (DTC) for a 2011 Nissan Altima Sedan indicates a problem with the Throttle Position Sensor/Switch 2 Circuit High Input. The throttle position sensor (TPS) is a crucial component in the vehicle's electronic fuel injection system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). The ECM uses this data to determine the appropriate fuel injection and ignition timing for optimal engine performance.
