Wheel Speed Sensor Encoders
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The wheel speed sensor encoders are magnetized, toothed rings used to create a Hall-effect switch when combined with the wheel speed sensor. The front wheel speed sensor encoders are integrated into the front wheel bearing and are serviced with the front wheel bearing. The rear wheel speed sensor encoders are pressed onto the rear wheel axle shaft and are serviced separately from the axle shaft.
