Solution

1. Preparation

Ensure the vehicle is parked on a level surface with the ignition off.
Gather necessary tools and safety equipment.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

Locate the Wheel Speed Sensor:
- Depending on the affected wheel (front or rear), raise the vehicle using a jack and secure it with jack stands.
- Remove the wheel for better access to the sensor.
Remove the Old Sensor:
- Disconnect the electrical connector from the wheel speed sensor.
- Remove the mounting bolt(s) securing the sensor to the wheel hub or knuckle using a socket set.
- Pull the sensor straight out from its housing.
Install the New Sensor:
- Apply a small amount of dielectric grease to the O-ring of the new wheel speed sensor.
- Insert the new sensor into the housing, ensuring it is seated properly.
- Reinstall the mounting bolt(s) and torque them to the manufacturer’s specifications (typically around 7-10 ft-lbs, check service manual for exact values).
- Reconnect the electrical connector.

3. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes.
Drive the vehicle at low speeds in a safe area to allow the ABS system to recalibrate.
