Removal and Repair Procedure
When disconnecting the wheel speed sensor from vehicle wiring harness, be careful not to damage pins on connector.
1. Remove harness connector.
2. Remove sensor bolt and remove the speed sensor.
Removal
1. Remove wheel hub assembly from the vehicle.
2. Remove rotor with SST (0K670 990 AA0). Do not re-install a rotor which is removed.
Installation
1. Clean
ABS Speed Sensor attaching surface.
2. Install speed sensor.
Tightening torque : 7 lb-ft (9.5 N-m, 1 kg-m)
3. Install the wiring harness connector with wheel speed sensor cable.
Be sure speed sensor cable connector is fully seated and locked into vehicle wiring harness connector.
4. Check the air gap between the face of the wheel speed sensor and the top surface of the tonewheel.
Air gap : 0.005~0.059 in (0.127~1.5 mm)
5. Road test vehicle to ensure proper operator of the base and ABS brake system.
Installation
1. Position a new sensor rotor on wheel hub as shown.
Number of sensor rotor teeth : 54
2. Press rotor onto wheel hub with SST (0K201 660 001).
3. Reinstall wheel hub assembly to vehicle.
4. Check the air gap between the face of the wheel speed sensor and the top surface of the tonewheel.
Air gap : 0.005~0.059 in (0.127~1.5 mm)
5. Road test vehicle to ensure proper operation of the base an ABS brake system.
Inspection
1. Measure clearance.
Specified clearance : 0.005~0.059 in (0.127~1.5 mm)
2. Measure speed sensor resistance.
Resistance : 2530~2930 Ω
Inspection
1. Lift and properly support front of the vehicle.
2. From backside of wheel, closely inspect sensor rotor. Rotate wheel to examine all teeth.
3. Replace rotor if teeth are missing or damaged.
