Wheel Speed Sensor: Testing and Inspection
Wheel Sensor Inspection1. Remove the appropriate front driveshaft or rear driveshaft.
2. Check the magnetic encoder after cleaning the encoder. If necessary, replace the front wheel bearing or rear wheel bearing unit.
3. Measure the air gap between the wheel sensor and the magnetic encoder all the way around while rotating the encoder.
Standard:
Front/Rear: 0.5 - 1.5 mm (0.02 - 0.06 inch)
NOTE:
^ Install the wheel bearing with the magnetic encoder (brown color) toward the inside of the knuckle.
^ Remove any oil, grease, dust, or other foreign material from the encoder surface. Keep magnetic tools away from the encoder surface.
^ Be careful not to damage the encoder surface when you insert the wheel bearing.
