This summary uses the existing diagnostic information shown in full below.
This code means that one of the sensors that tells the car how much you are pressing the gas pedal is sending too much electricity, like turning the volume up too high on a radio.
The P11EF code indicates that the voltage from the throttle or pedal position sensor 'E' is higher than expected by the engine control module (ECM).
The throttle/pedal position sensor/switch 'E' is responsible for providing the ECM with the position of the throttle or pedal. When the voltage signal from this sensor is higher than the acceptable range, the ECM triggers the P11EF code. This could be due to a malfunctioning sensor, wiring issues, or a problem with the ECM itself.
• Check Engine Light is on
• Poor throttle response
• Reduced engine performance
• Faulty throttle/pedal position sensor
• Wiring issues such as shorts or open circuits
• Defective ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the throttle/pedal position sensor with a multimeter.
• Replace the throttle/pedal position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Honda Accord
• Toyota Camry
• Ford Focus
• Regular maintenance and inspection of the throttle system.
• Ensure connectors are secure and free from corrosion.
• Use quality replacement parts.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Get the vehicle inspected by a professional mechanic.
Check with the vehicle manufacturer for warranty coverage on the throttle system.
This code has been reported in vehicles with high mileage or those that have experienced electrical issues.
Moderate – The vehicle may still be drivable, but performance issues should be addressed soon to prevent further damage.
Driving with a malfunctioning throttle sensor can lead to reduced control over the vehicle, which may be unsafe.
• Vehicle at operating temperature
• Sensor connected and operational
The throttle/pedal position sensor is typically located on the throttle body or near the accelerator pedal.
Q: Can I drive with a P11EF code?
A: It's possible to drive, but it's not recommended as it may affect vehicle performance and safety.
Q: How do I reset the P11EF code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
