Code P0222 2008 Nissan Maxima Description

The P0222 diagnostic trouble code (DTC) for a 2008 Nissan Maxima indicates a problem with the Throttle Position Sensor/Switch 2 Circuit, specifically a low input signal. The throttle position sensor (TPS) is a crucial component that monitors the position of the throttle valve in the engine. This information is then relayed to the engine control module (ECM) to adjust fuel delivery and ignition timing, ensuring optimal engine performance.
