Vacuum Sensor

Vacuum Sensor is connected to brake booster. The sensor detects brake booster pressure and sends the voltage signal to the ABS actuator and electric unit (control unit). The sensor uses a silicon diaphragm which is sensitive to the change in pressure. As the pressure increases, the voltage rises.

EMCM judges force to depress a brake pedal for the stop/start system according to brake booster pressure sensor signal sent from ABS actuator and electric unit via CAN communication.
