Brake Pressure Sensor

Stability control uses it. It is often in the ABS unit. It helps detect braking intent. It allows features such as brake assist and hill hold to respond to how hard the driver brakes. Replacing the ABS unit usually includes this sensor. A fault often lights the ABS and stability warnings at the same time. Diagnosis starts with live data, comparing the reading with the pedal pressed and released.

A pressure element converts pressure into a signal.

Faults disable stability functions. Bleed brakes correctly after repair.
