Brake Booster Diaphragm Travel Sensor

The brake booster diaphragm travel sensor is a linear potentiometer used by the ABS module to monitor travel distance of the brake booster diaphragm. The sensor is hardwired to the ABS module by 3 circuits. One circuit is for the 5 volt sensor supply, one circuit is for sensor ground and one circuit is for sensor output. The sensor output ranges from 0.2 volt to 4.7 volts, depending on how far the brake booster diaphragm travels.
