Brake Pedal Position Sensor
The chassis or brake control module has detected an implausible signal from the brake pedal position sensor. Modern brake systems use this sensor for brake assist, regenerative braking and adaptive cruise control functions.
Affected components
- Brake pedal position sensor
- Brake control module
- Brake pedal assembly
Common causes
- High likelihood: Pedal position sensor failed
- Medium likelihood: Sensor not calibrated after replacement
- Low likelihood: Wiring or connector fault
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
