Code P0223 2006 Nissan Altima Sedan Description

The P0223 diagnostic trouble code (DTC) for a 2006 Nissan Altima Sedan indicates a problem with the Throttle Position Sensor/Switch 2 Circuit, specifically a high input signal. 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 this information to the engine control module (ECM). The ECM uses this data to determine the appropriate fuel delivery and ignition timing for optimal engine performance.
