P2299 Code: Brake Pedal Position/Accelerator Pedal Position Incompatible

The P2299 code means the computer saw the brake and the accelerator pressed at the same time. For safety, it reduces engine power. The cause is often as simple as a floor mat or a driver resting a foot on the brake, but a faulty brake switch is also common.

What the P2299 code means

Many vehicles have a brake priority function: if the driver presses the brake while accelerating, the computer closes the throttle so the brake wins. When it detects that situation, it stores the P2299 code.

It can show up from driving with the left foot resting on the brake, from a floor mat pushing on a pedal, or from a faulty brake switch that says the brake is pressed when it is not.

Because the engine cuts power on purpose, the loss of power can be sudden. That is why it is worth finding the cause instead of ignoring the light.

P2299 code symptoms

  • Momentary loss of power.
  • Check engine light on.
  • Brake lights that stay on if the switch is faulty.

Likely causes of the P2299 code

  1. Both pedals pressed at once by the driving habit or a floor mat.
  2. Brake switch out of adjustment or faulty. Confirm it with the tests in the diagnosis section.
  3. Accelerator pedal sensor that does not return to rest.
  4. Wiring. Look for rubbing against the engine, the chassis or the exhaust.

How to diagnose the P2299 code step by step

  1. Check the floor mat and that both pedals return to rest.
  2. Read the brake switch state in live data.
  3. Check the brake lights with the pedal released.

How to fix the P2299 code

  • Reposition the floor mat and drive without resting your foot on the brake.
  • Adjust or replace the brake switch.
  • Clear the codes.

After the fix, make sure the P2299 code does not return over the next few days of normal driving and that the brake lights go out when you release the pedal.

Technical reference data

  • The brake switch usually has two circuits: one for the brake lights and one for the computer.
  • These are reference values only: check the manufacturer data for your vehicle.
