Sensor-To-Rotor Gap Adjustment

Raise and support vehicle. Remove 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. See Fig 1 . Front sensor clearance should be .008-.390" (0.2-1.0 mm). Rear sensor clearance should be .012-.035" (0.3-0.9 mm). If clearance is not within specification, loosen sensor mounting bolt. Adjust sensor position until clearance is within specification. Tighten sensor mounting bolt to 84 INCH lbs. (120 N.m).
