Code P2118 Mitsubishi Description

The P2118 code for Mitsubishi vehicles refers to an issue with the Throttle Actuator Control Motor Current Range/Performance. This means that the Engine Control Module (ECM) has detected that the current going to the throttle actuator control motor is outside of the expected range or is not performing as it should. The throttle actuator control motor is responsible for controlling the throttle plate, which regulates the amount of air entering the engine. When this system malfunctions, it can have a significant impact on the vehicle's performance.
