When your 2022 Jeep Grand Cherokee's electronic throttle control stops responding and code P2111 is stored, the PCM has detected that the throttle actuator is stuck open or unable to reach its commanded position. This condition causes severe drivability issues and often triggers limp mode.
Understanding Code P2111
P2111 is different from APP sensor codes—it specifically relates to the throttle body itself. The code sets when the PCM commands a certain throttle position but the actual position (measured by the TPS sensors) doesn't match. The throttle may be stuck open due to mechanical or electrical issues.
What Causes Throttle Actuator Problems
The 2022 Grand Cherokee with its 3.6L Pentastar V6 or 5.7L Hemi can experience P2111 from: a faulty throttle body motor, binding throttle plate due to carbon buildup, foreign object lodged in the throttle body, failed throttle position sensors, wiring damage in the throttle control circuit, or PCM driver issues. The electronic throttle control light (ETC) often illuminates along with the check engine light.
Symptoms of Stuck Open Throttle
You'll experience: high idle that won't come down, the engine racing without pedal input, poor or no response when pressing the gas, the vehicle entering limp mode, and potentially the engine stalling when slowing down. The ETC lightning bolt warning light appears on the instrument cluster.
Diagnosis Protocol
Diagnosis begins with monitoring throttle position vs. commanded position. If the PCM commands 15% throttle but actual position shows 45%, the throttle is stuck partially open. Technicians test the throttle motor operation by commanding actuator tests through the scan tool and observing throttle plate movement.
Repair Solutions
Throttle body replacement is the most common repair for P2111. The 2022 Grand Cherokee's throttle body is a dealer part that comes pre-assembled. After installation, the PCM must relearn minimum throttle position and idle speed through an automated procedure. Clearing codes and test driving verifies the repair.
