P2299
Brake Pedal Position / Accelerator Pedal Position Incompatible
- Severity
- High
- Driving
- Drivable — book it in
The module has seen the brake and the accelerator pressed together in a way it does not accept. Modern vehicles include a brake override: if both pedals are pressed, the brake wins and the throttle is closed. This code records that the condition occurred - and there are two very different explanations, one harmless and one not.
Possible causes
- CommonDriver braking with the left foot, or resting a foot on the brake pedal
- CommonMisadjusted or failed brake pedal switch reporting the brake pressed when it is not
- CommonAccelerator pedal position sensor fault
- PossibleSticking accelerator pedal or throttle linkage
- PossibleFloor mat or object fouling a pedal
- PossibleWiring fault on either pedal circuit
What you might notice
- Sudden loss of power when braking
- Engine dropping to idle unexpectedly
- Brake lights on when the pedal is not pressed
- Reduced power warning
- Check engine light on
What to check, in order
- Check whether anything is fouling the pedals - a loose floor mat, an object under the pedal, or a mat fitted on top of the original. That is the cause you must rule out first, because it is the one that can hold the accelerator down.
- Check whether the brake lights work and go out when the pedal is released. A brake switch stuck on makes the module believe you are braking constantly.
- Ask about driving style. Left-foot braking, or resting a foot on the brake pedal, sets this code with nothing wrong at all.
- Watch both pedal positions on the live data screen while operating each pedal separately.
- Check the accelerator pedal moves freely and returns fully.
