Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Gather necessary tools: OBD-II scanner, multimeter, socket set, and safety glasses.

2. Remove the Wheel

Sub-steps:
1. Loosen the lug nuts on the right front wheel.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace the Wheel Speed Sensor

Sub-steps:
1. Locate the right front wheel speed sensor mounted near the brake rotor.
2. Disconnect the sensor's electrical connector.
3. Remove the sensor from its mounting location using a socket or wrench.
4. Install the new wheel speed sensor in the reverse order of removal, ensuring it is securely fastened.
5. Reconnect the electrical connector.

4. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specified value (usually around 80-100 ft-lbs).
3. Start the engine and check for error codes using the OBD-II scanner.
4. Take the vehicle for a test drive to ensure the ABS and traction control systems are functioning correctly.
