P2112 code indicates a problem with the throttle actuator control system being stuck closed, which can result in limited engine performance.
P2112 Throttle Actuator Control System – Stuck Closed
Code symptoms P2112.
1. Engine idling rough or stalling.
2. Lack of acceleration.
3. Reduced engine power.
4. Check Engine Light.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.
Causes of the code P2112.
1. Faulty throttle actuator control module
2. Stuck throttle plate due to debris or carbon buildup
3. Wiring or electrical connection issues in the throttle actuator control system
4. Mechanical failure of the throttle actuator itself
5. Engine control module (ECM) software or calibration issues
Code Solutions P2112.
1. Inspect the throttle actuator for any signs of physical obstruction or damage. Remove any debris or blockages that may be causing the actuator to remain stuck closed.
2. Check for any loose or disconnected electrical connectors related to the throttle actuator control system. Make sure all connections are secure and free of corrosion.
3. Perform a throttle body cleaning to remove any carbon buildup or debris that may be causing the actuator to stick. This can help improve the throttle response and prevent the actuator from getting stuck closed.
4. Test the throttle position sensor (TPS) to ensure it is functioning properly. A faulty TPS can send incorrect signals to the throttle actuator, causing it to remain stuck closed.
5. If the issue persists, consider replacing the throttle actuator assembly. A malfunctioning or worn-out actuator may not be able to operate correctly, leading to the stuck closed condition.
