What P2299 means
P2299 means the vehicle has seen the brake and the accelerator pressed together in a way it treats as implausible; engine torque is usually cut as a brake-override measure. GM documents the check in the brake control module of 2020 models with a pedal travel sensor: the code sets when the travel signal is not zero while the accelerator is applied above 4.47 mph (7.2 km/h) for 0.12 s, Type A. An FCA parts tip states it is mostly caused by drivers resting their left foot on the brake and warns against replacing the pedal; many FCA flash bulletins, e.g. 18-007-14 for the Fiat 500, and Nissan bulletin NTB17-063 (Titan XD, Cummins 5.0 L) clear it by reprogramming. A misadjusted brake light switch can also trigger it.
P2299 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.2 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2299
- Engine power drops while braking and accelerating together
- Check engine light
- Car does not respond to the accelerator for a moment
Common causes of P2299
- Most likelyDriver resting a foot on the brake while accelerating
- PossibleControl module software needing an update
- PossibleBrake light switch or pedal travel sensor misadjusted or sticking
- Less likelyFloor mat or object keeping a pedal partly pressed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2299 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 99 | The exact fault in that area. |
What to do next
- Note P2299 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2299
What does P2299 mean?
P2299 means "Brake Pedal Position/Accelerator Pedal Position Incompatible". P2299 means the vehicle has seen the brake and the accelerator pressed together in a way it treats as implausible; engine torque is usually cut as a brake-override measure. It is a generic code, so it means the same on every make.
Is it safe to drive with P2299?
Drive gently and only to a workshop. With P2299 the car can go into limp mode (reduced power) to protect itself.
Will P2299 fail an emissions test?
P2299 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2299 to fix?
Difficulty: easy. A typical repair takes 0.2 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2299 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
