Code P0222 2008 Nissan Sentra Description

The P0222 diagnostic trouble code (DTC) for a 2008 Nissan Sentra 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 of the vehicle's electronic fuel injection system, as it monitors the position of the throttle valve and sends signals to the engine control module (ECM) to adjust fuel delivery and ignition timing. The TPS is typically located on the throttle body and consists of a sensor and a potentiometer.
