Wheel Speed Sensor: Testing and Inspection
Wheel Sensor Inspection1. Clean the magnetic encoder, and make sure no metal or other debris is stuck to the magnetic encoder surface.
2. Check the magnetic encoder (A) for damage. If cracked or damaged, replace the encoder (wheel bearing).
^ Front wheel bearing replacement.
^ Rear wheel bearing replacement.
3. Measure the air gap between the wheel sensor (B) and the magnetic encoder all the way around while rotating the encoder.
Standard:
Front: 1.0 - 1.7 mm (0.04 - 0.07 in.)
Rear: 0.9 - 1.8 mm (0.04 - 0.07 in.)
