P2135 on Chrysler
Throttle/Pedal Position Sensor Voltage Correlation
P2135 on Chrysler vehicles indicates throttle/pedal position sensor voltage correlation. Au7o has documented this code across 1 Chrysler model — most commonly on 200. 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. Typical repair costs on Chrysler range from $30 to $400, depending on the specific model and root cause.
Common Causes of P2135
- •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)

- Engine Stalling at Idle (Electronic Throttle Body)2011-2017
The Chrysler 200 experiences intermittent engine stalling at idle, particularly when decelerating to a stop or sitting at traffic lights. The electronic throttle body accumulates carbon buildup that restricts airflow at idle, and the throttle position sensor can drift out of calibration. The 2.4L 4-cylinder is most commonly affected but the 3.6L V6 is also susceptible. The stall often occurs without a check engine light, making diagnosis frustrating.

What does P2135 mean on 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 specifically, this code is documented across 1 model.
