Wheel Speed Sensor Replacement- Front

Removal Procedure
1. Raise and support the vehicle. Refer to Vehicle Lifting.





2. Remove the Bolt/Screw (2) from the steering knuckle (1).
3. Remove the wheel speed sensor (3) from the steering knuckle (1).





4. Remove the cable (3) for the wheel speed sensor from the clips on the spring strut and the wheel housing.
5. Remove the wheel speed connector (1) from the wiring harness connector (2).
6. Remove the wheel speed sensor from the vehicle.

Inspection Procedure
^ Inspect for the following on the sensor face:
- Inspect for an accumulation of metallic particles.
- Clean the sensor as required.
- Inspect for an accumulation of dirt.
- Clean the sensor as required.
- Inspect for an accumulation of grease.
- Clean the sensor as required.
- Inspect for an accumulation of other contaminants.
- Clean the sensor as required.
^ Inspect the sensor face for evidence of damage. Inspect the sensor for contact with the toothed sensor ring. The sensor should not contact the toothed sensor ring. Determine and correct the cause of the damage when damage is evident. Replace the sensor if damage interferes with proper operation.

Installation Procedure

Notice:
^ The wheel speed sensor is a tight fit and is to be pushed in by hand. DO NOT force the sensor into position, as damage to the sensor could result.
^ Wheel speed sensors must be given an anti corrosion coating before installation to prevent corrosion. Use silicone grease P/N 12345579 or equivalent.





1. Install the wheel speed connector (1) to the wiring harness connector (2).
2. Install the cable (3) for the wheel speed sensor into the clips on the spring strut and the wheel housing.





3. Install the wheel speed sensor (3) into the steering knuckle (1).

Notice: Refer to Fastener Notice in Service Precautions.

4. Install the speed sensor Bolt/Screw (2).
Tighten the speed sensor bolt/screw to 8 Nm (71 inch lbs.).

Notice: Proper installation of the wheel speed sensor harness is critical to continued system operation. Failure to install the harness in brackets as shown may result in contact with moving parts, spark plug wires, and/or over extension of the wires, resulting in circuit damage.

5. Lower the vehicle.
6. Perform the Diagnostic System Check - ABS.
