Code P0223 2006 Infiniti G35 Description

The P0223 code on a 2006 Infiniti G35 indicates a problem with the Throttle Position Sensor/Switch 2 Circuit, specifically a high input signal. The throttle position sensor (TPS) is a crucial component in the vehicle's fuel management system, as it monitors the position of the throttle valve and sends this information to the engine control module (ECM). The ECM uses this data to adjust the air-fuel mixture for optimal engine performance.
