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.
Brake Pressure Sensor
1.Brake pressure sensor
A brake pressure sensor is installed in the hydraulic unit to determine the degree of pressure build up in the braking system. It is installed in the front axle brake circuit.
The sensor receives its power supply from the ABS ECU and produces a linear voltage input signal ranging from 0.5 to 4.5 volts depending on the brake pressure in the circuit.
The brake pressure sensor is used for emergency brake assist and to calculate brake torque applied to each wheel for all DSC functions. Torque is calculated using engine torque from the ECM, gear selected from the EAT ECU and range selected from the transfer box ECU. The sensor is also used for brake temperature calculation.
