P2112 on Chrysler by model: symptoms, diagnosis and fix
The Chrysler 200 experiences intermittent engine stalling at idle, particularly when decelerating to a stop or sitting at traffic lights. On 2011 models with the 3.6L V6, NHTSA investigation PE12-016 found the PCM could run an evaporative-emissions purge monitor check at idle, creating an overly rich vapor condition that stalls the engine; carbon buildup in the electronic throttle body is a further common cause of low idle and stalling on both the 2.4L and 3.6L as the cars age. The stall often occurs without a check engine light, making diagnosis frustrating.
Common Symptoms
- Engine stalls when coming to a stop
- RPM drops very low then engine dies
- Rough or surging idle
- Stalling without a check engine light
- Engine restarts immediately after stalling
How to Fix
On a 2011 200 with the 3.6L V6, first confirm the PCM reprogramming customer satisfaction campaign (bulletin sent to dealers September 28, 2012 after NHTSA PE12-016) has been done; it is free at the dealer. Clean the electronic throttle body with CRC throttle body cleaner — remove the air intake hose and spray the butterfly valve and bore while a helper opens the throttle plate. After cleaning, perform an idle relearn: key on (engine off) for 30 seconds, then start and let idle for 5 minutes without touching the gas pedal. If stalling persists, have the dealer reflash the PCM with the latest calibration and inspect the throttle body for TPS sensor failure. Replacement throttle body costs $200-$400.

Frequently asked questions
What does P2112 mean on a Chrysler?
P2112 stands for "Throttle Actuator Control System - Stuck Closed." 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. On Chrysler it is documented across 1 model: 200.
What are the most common causes of P2112?
The most common causes of P2112 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P2112 on a Chrysler?
Published repair estimates on Chrysler range from $30 to $400 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
