What does this fault code mean?
This code concerns accelerator pedal position sensor A, where the signal from the sensor is too high. Contact faults or a damaged sensor can cause it, affecting throttle response.
Possible causes
- Contact resistance or oxidation in the connectors
- Damaged accelerator pedal position sensor
What you can do
- 1Read the diagnostic and fault status for the code with the ignition on. Clear the code and road test the vehicle to see whether it returns
- 2Check the connector at the accelerator pedal position sensor for contact resistance and oxidation
- 3If you have a diagnostic tool: read the accelerator pedal signal in live data while pressing the pedal. A value that does not follow the pedal suggests the sensor is damaged
- 4If the connector is in order and the fault remains, have a workshop check or replace the accelerator pedal position sensor
Symptoms you may notice4
- A message is shown in the display
- Poor acceleration, the engine feels sluggish
- The engine has poor performance and lacks power, especially when starting
- The engine hesitates, surges or runs unevenly during acceleration
What the fault can affect1
- Engine torque is limited
General guidance for car owners. Diagnosis on the car can point to a different cause.
