P2111 on Jeep
Throttle Actuator Control System - Stuck Open
P2111 on Jeep vehicles indicates throttle actuator control system - stuck open. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. This code sets when the throttle actuator control (electronic throttle) system detects that the throttle plate is stuck in an open position and is not closing as commanded. Modern engines use a 'drive-by-wire' throttle where a motor moves the throttle plate based on accelerator pedal input, and dual position sensors confirm its actual angle. When the computer commands the throttle to close but the sensors show it remaining open, it sets this code and typically forces the engine into a reduced-power 'limp' mode for safety. It generally points to a mechanical bind, a failing throttle motor, or sensor issues inside the throttle body.
Common Causes of P2111
- •Carbon buildup binding the throttle plate
- •Faulty throttle body motor or actuator
- •Failed throttle position sensor inside the throttle body
- •Stuck or damaged throttle plate return mechanism
- •Wiring or connector fault at the throttle body
- •Debris or foreign object obstructing the throttle plate
- •Faulty engine control module driver circuit

- 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.

What does P2111 mean on Jeep?▼
P2111 stands for "Throttle Actuator Control System - Stuck Open."
