Calculate the clearance between the front ABS wheel-speed sensor and the ABS sensor rotor using the following formula:
Clearance (mm {IN}) = A-14 {0.55}
Verify that the clearance between the ABS sensor rotor and the ABS wheel-speed sensor is as indicated below.
- If there is any malfunction, replace it.
  Clearance
- 3-1.1 mm {0.02-0.04 in}
