Code P0223 2006 Nissan Maxima Description

The P0223 diagnostic trouble code (DTC) in a 2006 Nissan Maxima indicates that there is a high input signal detected in the throttle position sensor/switch 2 circuit. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve and sends signals to the engine control module (ECM) to adjust fuel delivery and ignition timing. In this case, a high input signal suggests that the voltage reading from the TPS is higher than the normal operating range, which can lead to various performance issues.
