Code P0223 2005 Nissan Altima Sedan Description

The P0223 diagnostic trouble code (DTC) for a 2005 Nissan Altima Sedan indicates an issue with the Throttle Position Sensor/Switch 2 Circuit High Input. This code is specifically related to the throttle position sensor (TPS) in the vehicle. The TPS is a crucial component that monitors the position of the throttle valve and sends this information to the engine control module (ECM) to adjust fuel delivery and ignition timing. When the ECM detects a high input signal from the TPS, it triggers the P0223 code.
