Code P0222 2005 Infiniti G35 Description

The P0222 diagnostic trouble code (DTC) for a 2005 Infiniti G35 indicates a problem with the Throttle Position Sensor/Switch 2 Circuit Low Input. The throttle position sensor (TPS) is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle valve and sending this information to the engine control module (ECM). This data is used by the ECM to determine the appropriate fuel delivery and ignition timing for optimal engine performance.
