Code P0223 2002 Nissan Altima Sedan Description

The P0223 diagnostic trouble code (DTC) for a 2002 Nissan Altima Sedan indicates a problem with the Throttle Position Sensor/Switch 2 Circuit having a 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 this information to the engine control module (ECM). The ECM uses this data to determine the appropriate air-fuel mixture for combustion in the engine.
