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.
