Description of DTC code P2299

The Powertrain Control Module (PCM) identifies brake application when the ignition switch is in the ON position, and the Accelerator Pedal Position (APP) sensor does not have interruptions or faults. The PCM must observe a fixed pedal opening to make such recognition, which may be provisional or permanent.

The OBDII DTC P2299 is set when the PCM detects that the brake pedal is depressed. At the same time, the APP Sensor shows that the throttle is open.

  • The vehicle goes into limp mode.
  • When starting the engine, black smoke comes out of the exhaust.
  • The cruise control system does not work efficiently.
  • The rear brake indicator lights remain illuminated, even when they should not be.
