Sensor-To-Rotor Gap Adjustment

  1. Raise and support vehicle. Remove wheel assembly. On rear axle, remove caliper assembly and support with wire. Remove rotor. Inspect sensor pole piece for damage. Repair if necessary. If sensor pole piece is okay, check wheel speed sensor-to-rotor gap.
  2. 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).
