Wheel Speed Sensor: Description and Operation

Fig. 1  ABS System Components

    Refer to Fig. 1 for system component locations.

    These sensors located on the front steering knuckles and under the wheel bearing dust caps on the rear wheels, send a low voltage signal to the ECU.
This signal is produced by rotating a toothed ring around the sensor pole piece, which produces a magnetic field that increases and decreases in
magnitude.
