Wheel Speed Sensor: Testing and Inspection

VSA System Wheel Speed Sensor Inspection

1. Inspect the front and rear pulsers for chipped or damaged teeth.

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