P2112 on Dodge
Throttle Actuator Control System - Stuck Closed
P2112 on Dodge vehicles indicates throttle actuator control system - stuck closed. Au7o has documented this code across 1 Dodge model — most commonly on Dart. 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. Typical repair costs on Dodge range from $50 to $600, depending on the specific model and root cause.
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

- Engine Stalling at Idle (Software and Throttle Body Related)2013-2016
Darts across all engine options experience random stalling at idle, particularly when coming to a stop or sitting at traffic lights. The issue stems from a combination of electronic throttle body carbon buildup and PCM software calibration problems. The 2.0L and 2.4L engines are most commonly affected. Several TSBs have been issued addressing idle quality.
