What Does P2299 Mean?
The PCM has detected simultaneous signals from both the brake pedal position sensor and accelerator pedal position sensor that are logically incompatible. This indicates both pedals are being pressed simultaneously or there is a sensor/circuit malfunction.
Safety Warning
This is a critical safety code. The vehicle may enter limp mode or restrict acceleration to prevent unintended acceleration scenarios. Repair immediately before driving.
Common Causes
35%
Faulty brake pedal position switch or sensor
25%
Misadjusted or binding brake pedal switch staying engaged
20%
Faulty accelerator pedal position sensor sending incorrect signal
15%
Wiring issue causing false signal from brake or accelerator circuit
5%
Brake pedal return spring weak or pedal binding mechanically
Diagnostic Steps
1
Step 1: Monitor brake pedal position and accelerator pedal position sensors simultaneously on scan tool
2
Step 2: Physically inspect brake pedal for proper return and clearance when released
3
Step 3: Test brake light switch operation and adjustment at pedal assembly
4
Step 4: Verify accelerator pedal position sensor voltages at idle (typically 0.5-0.9V)
5
Step 5: Check wiring and connectors at both brake and accelerator pedal sensors for damage
Estimated Repair Cost
$100 - $500
Parts + labor, varies by vehicle and location
The PCM has detected simultaneous signals from both the brake pedal position sensor and accelerator pedal position sensor that are logically incompatible. This indicates both pedals are being pressed simultaneously or there is a sensor/circuit malfunction.
The most common cause of P2299 (Brake Pedal Position/Accelerator Pedal Position Incompatible) is: Faulty brake pedal position switch or sensor
Typical repair costs for P2299 range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This is a critical safety code. The vehicle may enter limp mode or restrict acceleration to prevent unintended acceleration scenarios. Repair immediately before driving.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2299 to identify the root cause.
