Wheel Speed Sensor Encoders

The wheel speed sensor encoders are magnetized, toothed rings used to create a Hall-effect switch when combined with the wheel speed sensor. On RWD vehicles, the front encoders are part of the front wheel hub and bearing while the rear encoders are part of the rear axle halfshaft. On 4WD vehicles, all 4 encoders are part of the front and rear halfshafts.
