C0075 Brake Pedal Position Performance

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

A performance code for the brake pedal position input, set when the signal is present but behaves implausibly, for example it does not change as expected, lags, or disagrees with brake pressure and the switch. The stability and brake modules use pedal position to blend regenerative and friction braking and to arm or cancel driver-assist functions. Manufacturers map this code to the input their system uses: Subaru documents C0075 as a concern with the wheel-cylinder pressure-sensor signal in the EyeSight dynamics-control hydraulic module, while some European systems tie it to the brake-light switch feeding the ESP unit. A fault degrades regenerative blending and assist functions and sets the ABS/ESC warning lamp while base braking remains. The entry follows the SAE J2012 generic definition.

Likely causes

Pedal/pressure sensor signal implausible
Pedal or switch out of adjustment
Harness or connector fault

Symptoms

  • Degraded regenerative braking blend
  • Driver-assist functions limited
  • ABS/ESC warning lamp on
