P11EF Code - Throttle/Pedal Positio Sensor/Switch 'E' Circuit Voltage High
Quick Answer
The accelerator pedal position is monitored separately by 2 individual sensors. Common causes include Faulty Accelerator Pedal, Accelerator Pedal harness is open or shorted, Accelerator Pedal circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P11EF Description
Each change in the accelerator-pedal position is transmitted to the engine-management control unit with a maximum lag of 50 milliseconds. Sensor signals are transmitted in analog form. The engine-management control unit monitors the two input signals from the sensors and compares them for plausibility (factors such as mutual synchronicity, linearity, etc.).
The Digital Motor Electronics (DME) diagnosis the voltage at the Accelerator Pedal Module Pedal Sensor 2. The Diagnostic Trouble Code (DTC) is detected whenever the voltage on pedal sensor 2 becomes greater than the limit value. Limit value: 0.5 multiplied by 4.75 V.
What are the Possible Causes of the DTC P11EF?
- Faulty Accelerator Pedal
- Accelerator Pedal harness is open or shorted
- Accelerator Pedal circuit poor electrical connection
- Faulty Accelerator Pedal Module
How to Fix the DTC P11EF?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P11EF code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P11EF Code
1. What are the common symptoms of OBDII code P11EF?
The common symptoms of OBDII code P11EF include reduced engine power, hesitation or stalling when accelerating, and the illumination of the Check Engine Light.
2. What causes OBDII code P11EF to trigger?
OBDII code P11EF is triggered when the Engine Control Module (ECM) detects a high voltage signal from the throttle/pedal position sensor/switch 'E' circuit, indicating a potential issue with the sensor or circuit.
3. How can I diagnose the cause of OBDII code P11EF?
Diagnosing the cause of OBDII code P11EF involves inspecting the throttle/pedal position sensor/switch 'E' circuit for any damaged wiring, loose connections, or sensor malfunctions. Using a scan tool to read live data can help pinpoint the issue.
4. What are the possible repair solutions for OBDII code P11EF?
Repair solutions for OBDII code P11EF may include replacing a faulty throttle position sensor, repairing damaged wiring or connectors in the 'E' circuit, or resetting the ECM after making necessary repairs.
5. Can driving with OBDII code P11EF cause further damage to the vehicle?
Continuing to drive with OBDII code P11EF may lead to poor engine performance, reduced fuel efficiency, and potential damage to other engine components over time. It is recommended to address the issue promptly.
6. Is it safe to reset the ECM to clear OBDII code P11EF?
Resetting the ECM to clear OBDII code P11EF may temporarily turn off the Check Engine Light, but if the underlying issue is not addressed, the code is likely to reappear. It's important to diagnose and repair the root cause first.
7. How much does it typically cost to repair OBDII code P11EF?
The cost to repair OBDII code P11EF can vary depending on the specific cause of the issue, the labor rates in your area, and whether any parts need to be replaced. It's advisable to consult with a mechanic for an accurate estimate.
8. Can I drive my vehicle with OBDII code P11EF if the symptoms are not severe?
While it may be possible to drive the vehicle with OBDII code P11EF if the symptoms are not severe, it is not recommended. Ignoring the issue can lead to further problems and potential safety hazards on the road.
9. How long does it take to repair OBDII code P11EF?
The time it takes to repair OBDII code P11EF can vary depending on the complexity of the issue and the availability of parts. Some repairs may be completed within a few hours, while others may take longer.
10. Are there any preventative measures to avoid OBDII code P11EF in the future?
To help prevent OBDII code P11EF in the future, it's important to perform regular vehicle maintenance, including checking and cleaning throttle position sensors, inspecting wiring for damage, and addressing any issues promptly to avoid escalation.
