Mazda CX-5 Service & Repair Manual: Brake Fluid Pressure Sensor

Mazda CX-5 Service & Repair Manual / Brakes / General / Brake Fluid Pressure Sensor

Purpose/Function

The brake fluid pressure sensor detects the fluid pressure from the master cylinder and transmits it to the DSC HU/CM.

Construction

The brake fluid pressure sensor is built into the DSC HU/CM. Therefore if there is any malfunction of the brake fluid pressure sensor, replace the DSC HU/CM.
