Wheel Speed Sensor: Testing and Inspection

Wheel Sensor Inspection
1. Inspect the front and rear pursers for chipped or damaged teeth.





2. Measure the air gap between the wheel sensor and purser all the way around while rotating the purser. Remove the rear brake disc to measure the gap on the rear wheel sensor. If the gap exceeds 1.0 mm (0.04 inch), check for a bent suspension arm.
