Clearance Inspection

1. Remove the rear ABS wheel-speed sensor.
2. Measure the distance between the rear ABS wheel-speed sensor installation surface and the ABS sensor rotor. This is dimension A.
3. Calculate the clearance between the front ABS wheel-speed sensor and the ABS sensor rotor using the following formula:

   Clearance (mm {in}) = A-15.0 {0.60 in}

4. Verify that the clearance between the ABS sensor rotor and the rear ABS wheel-speed sensor is as indicated below.

• If there is any malfunction, replace it.

Clearance 

• 0.3-1.1 mm {0.012-0.043 in}
