- Generic OBD-II code · Powertrain

- How the car detects it
- 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.
