Brake Booster Vacuum Sensor

The brake booster vacuum sensor is a piezoelectric device used by the ABS module to monitor the vacuum in the brake booster. The sensor is located on the brake booster and the sensor output ranges from 0.2 volt to 4.9 volts, depending on the amount of vacuum in the booster.
