Wheel Sensor Inspection

Inspect the front and rear pulsers for chipped or damaged teeth.
Measure the air gap between the wheel sensor and the pulser all the way around while rotating the pulser. Remove the rear brake disc to measure the gap on the rear wheel sensor. If the gap exceeds 1.0 mm (0.04 in.), check for a bent suspension arm.
