DESCRIPTION AND OPERATION

Wheel Speed Sensors

1 Wheel speed sensor
2 Location bolt
3 Cable clip

4 Cable clip
5 Grommet

The wheel speed sensors are 2 wire Hall Effect type sensors. These sensors picks up on a 48 pulse incremental wheel 
speed sensor pole wheel on the drive shaft. 48 pulses = one complete wheel revolution. The sensor receives a 
stabilized 8 volt power supply to hall element on one wire, ground path for sensor through second wire back to the 
ABS ECU. The signal is generated by the pulse wheel affecting voltage flow through the hall element creating a low 
of 0.75 and a high of 2.5 volts. The sensors provide immediate vehicle speed recognition.
