Speed Sensor

SPEED SENSOR




The speed sensor is single pole, variable reluctance pick up, mounted in the rear differential carrier. An exciter ring is press fit on the differential ring gear and provides the signal for the sensor.
The signal generated is proportional to the average speed of the rear wheels and is used by the electronic brake control module (EBCM) to determine locking tendencies of the rear wheels.
