Wheel Speed Sensor: Testing and Inspection
Rear ABS Wheel-Speed Sensor Inspection
REAR ABS WHEEL-SPEED SENSOR INSPECTION
Installation Visual Inspection
1. Inspect for the following:
^
If there is any malfunction, replace the part.
(1) Excessive looseness or play of the ABS wheel-speed sensor
(2) Deformation of the ABS wheel-speed sensor
(3) Deformation or damage of the ABS sensor rotor
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 rear ABS wheel-speed sensor and the ABS sensor rotor using the following formula:
Clearance (mm {in}) = A -13.9 (0.547)
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
1.46 mm (0.057 in) or less
Sensor Output Value Inspection
Caution:
^
Resistance inspection using other testers may cause damage to the ABS wheel-speed sensor internal circuit. Be sure to use the M-MDS to
inspect the ABS wheel-speed sensor.
1. Turn the ignition switch off.
2. Connect the M-MDS to the DLC-2.
3. Select the following PIN using the M-MDS:
^
LR WSPD
(LR wheel-speed sensor)
^
RR WSPD
(RR wheel-speed sensor)
4. Start the engine and drive the vehicle.
5. Verify that the display of the M-MDS shows the same value as the speedometer.
