P2135 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 P2135 mean on a Chrysler?
P2135 stands for "Throttle/Pedal Position Sensor Voltage Correlation." P2135 means the powertrain computer detected that the two throttle position (TP) or accelerator pedal position sensors disagree with each other. Drive-by-wire systems use redundant sensors so the PCM can cross-check the throttle or pedal reading for safety; if the two signals don't correlate within an expected range, this code sets. As a fail-safe, the vehicle often enters a reduced-power 'limp' mode, causing sluggish acceleration, a stuck or hesitant throttle, and a warning light. Because it affects throttle control, it should be addressed promptly. On Chrysler it is documented across 1 model: 200.
What are the most common causes of P2135?
The most common causes of P2135 are: Faulty throttle position sensor / throttle body assembly, Faulty accelerator pedal position sensor, Damaged wiring or connectors at the throttle body or pedal, Corroded or loose connector terminals, Poor ground or reference voltage problem, Carbon buildup binding the electronic throttle plate, Failed PCM (rare). The specific cause varies by vehicle.
How much does it cost to fix P2135 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.
