P11CE Possible Causes
- Faulty accelerator pedal
- Accelerator pedal harness is open or short-circuited
- Poor electrical connection of the accelerator pedal circuit
- Faulty accelerator pedal module
How is code P11CE repaired?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.
Possible Symptoms
- Engine light on (or engine service warning light soon)
P11CE Meaning
The accelerator pedal position is separately monitored by 2 individual sensors. Two sensors are used to ensure redundancy, implement monitoring functions, and facilitate malfunction detection. The sensors record the accelerator pedal travel as angular deflection, with data transmitted directly to the engine management control unit as analog linear voltage curves for the pedal angle. The total pedal travel is mechanically expressed as 16° ± 0.5°.
Each change in accelerator pedal position is transmitted to the engine management computer with a maximum delay of 50 milliseconds. The sensor signals are transmitted in analog form. The engine management control unit monitors both sensor input signals and compares them for plausibility (factors such as mutual synchrony, linearity, etc.).
The digital motor electronics (DME) diagnose the voltage at sensor pedal 1 of the accelerator pedal module. The diagnostic trouble code (DTC) is detected if the voltage at pedal sensor 1 is below a lower threshold value. Lower threshold value: 0.51 V.
