Code P0222 2005 Nissan Pathfinder Description

The P0222 diagnostic trouble code (DTC) for a 2005 Nissan Pathfinder 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 (TPS) or throttle position switch (TPS 2). The TPS is a crucial component that monitors the position of the throttle valve and sends this information to the ECM to adjust fuel delivery and ignition timing. When the ECM receives a low input signal from the TPS 2 circuit, it can lead to various performance issues in the vehicle.
