Code P0222 2006 Infiniti G35 Description

The P0222 code for a 2006 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 that monitors the position of the throttle valve and sends this information to the engine control module (ECM). The ECM uses this data to determine the appropriate air-fuel mixture for combustion in the engine. When the TPS/Switch 2 Circuit is reporting a low input signal, it means that the voltage signal from the sensor is lower than expected, which can lead to various performance issues.
