Calculate the clearance between the rear ABS wheel-speed sensor and the ABS sensor rotor using the following formula:
Clearance (mm {IN}) = A-35.05 {1.380}
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 rear ABS wheel-speed sensor. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION (AWD) .)
