Solution

1. Preparation

Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel and Brake Assembly

Loosen the lug nuts on the front wheel using a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.
Remove the brake caliper and bracket, securing them out of the way (do not let them hang by the brake line).
Remove the brake rotor to access the wheel hub.

3. Inspect and Replace Wheel Speed Sensor

Locate the wheel speed sensor mounted on the wheel hub assembly.
Disconnect the electrical connector from the sensor.
Remove the mounting bolt securing the sensor to the hub.
Gently pull out the sensor from its housing.
Compare the old sensor with the new one to ensure compatibility.
Install the new wheel speed sensor by reversing the removal steps, ensuring it is seated correctly.

4. Reassemble Components

Reinstall the brake rotor and secure it.
Reattach the brake caliper and bracket, tightening to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specified torque value.

5. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and check for any new error codes using the OBD-II scanner.
Test drive the vehicle to ensure proper functionality of the wheel speed sensor and related systems.
