Code P0222 2008 Nissan Altima Sedan Description

The P0222 diagnostic trouble code (DTC) for a 2008 Nissan Altima Sedan refers to the Throttle Position Sensor/Switch 2 Circuit Low Input. This code indicates that the Engine Control Module (ECM) has detected a lower than expected voltage signal from the throttle position sensor or switch 2. The throttle position sensor (TPS) is a crucial component of the electronic throttle control system, as it monitors the position of the throttle valve and sends this information to the ECM. The ECM uses this data to determine the appropriate air-fuel mixture for optimal engine performance.
