Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Component Functional Description-Brake Pedal Simulator Pressure Sensor
eBOOSTER SYSTEMS ONLY: As the vehicle operator presses on the Brake Pedal on the eBooster system, the hydraulic/spring pressure is applied on the Brake Pedal Simulator Pressure Sensor. The Brake System Control Module (BSCM) monitors the signal from the Brake Pedal Simulator Pressure Sensor as one input to vehicle operator brake input. The Brake Pedal Simulator Pressure Sensor is rationalized against the signals from both internal Brake Pedal Position Sensor signals.
The Brake Pedal Simulator Pressure Sensor is internal to the Hydraulic Control Unit assembly and cannot be serviced separately.
