How to fix P2112 Code: Throttle Actuator Control System Stuck Closed
A P2112 code is set when the computer (ECM/PCM) detects the throttle is not in the expected position.
The Throttle Actuator is a DC motor controlled by the computer (ECM/PCM/TAC) that opens and shuts the throttle body plate (butterfly).
The Throttle Actuator Control (TAC) is all the components involved, including wiring, DC motor, butterfly, sensors, and computer (ECM/PCM/TAC)
If the throttle body is replaced, it may have a Throttle Relearn procedure.
Possible Causes of a P2112 Code:
Dirty or Bad Throttle Body (Needs Cleaned or Replaced)
Wiring (Open / Short / Fuse / Bad Connections)
Bad TAC Module (Some Vehicles the Actuator is Controlled by the ECM or PCM)
Bad Throttle Position Sensor or Pedal Position Sensor (Will Usually Get Another Code)
