Wheel Speed Sensor

Raise and support vehicle. Remove tire and wheel assembly. Inspect sensor pole piece for damage. Repair if necessary. If sensor pole piece is okay, check wheel speed sensor-to-rotor gap.
Using a feeler gauge, check clearance between speed sensor pole and rotor tooth surface. Gap should be 1.11-1.12" (28.2-28.5 mm). See Fig 1 or Fig 2 . See If clearance is not within specification, loosen sensor mounting bolt. Adjust sensor position until clearance is within specification. Tighten sensor mounting bolt.
