Code P0222 Mitsubishi Description

The P0222 diagnostic trouble code (DTC) in a Mitsubishi indicates that the throttle position sensor circuit is registering 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). This data is used by the ECM to calculate the appropriate air-fuel mixture for optimal engine performance.
