P2112 on Jeep
Throttle Actuator Control System - Stuck Closed
P2112 on Jeep vehicles indicates throttle actuator control system - stuck closed. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. P2112 means the throttle actuator control (electronic throttle) system is stuck in the closed position. On drive-by-wire engines the computer moves the throttle plate with an electric motor and confirms its position with sensors; when it commands the throttle open but the plate won't move past closed, this code sets. This usually triggers limp/failsafe mode with greatly reduced power, a poor or surging idle, or a no-acceleration condition. It points to a mechanical or electrical problem in the throttle body or its control circuit.
Common Causes of P2112
- •Carbon buildup or debris binding the throttle plate
- •Failed throttle body actuator motor
- •Faulty throttle position sensor inside the throttle body
- •Damaged or corroded throttle body connector/wiring
- •Loss of power or ground to the throttle body
- •Seized or mechanically stuck throttle plate
- •Faulty throttle control circuit in the PCM/ECM

- ETC Warning or Limp Mode - Read the DTC Before Buying a Throttle Body2011-2022
The electronic-throttle-control warning lamp and reduced-power or limp mode are protective responses, not a diagnosis that the throttle body has failed. Depending on the stored DTC and application, the factory path may lead to a stuck or contaminated throttle plate, throttle motor or position-sensor response, accelerator-pedal sensors, a five-volt supply fault, damaged wiring or terminals, or a PCM issue. The old card's thermostat shopping claim is not part of the cited ETC diagnostic path, and a throttle body should not be ordered from the warning lamp alone.
