Code P0222 2004 Infiniti G35 Description

The P0222 code on a 2004 Infiniti G35 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 throttle control system, as it monitors the position of the throttle pedal and sends signals to the engine control module (ECM) to adjust the throttle opening accordingly. In this case, a low input signal from the TPS can lead to issues with the engine's performance, fuel efficiency, and overall drivability.
