Control Pressure Switch

The control pressure switch, mounted on the hydraulic unit, monitors booster servo circuit pressure and provides a signal to the EBCM when boost pressure reaches approximately 400 psi (2,750 kPa). This input is used by the EBCM for verifying proper operation of the booster/master cylinder assembly. The control pressure switch is a serviceable component. A short harness and 2-pin connector are used to connect the control pressure switch to the sensor block.
