Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety before starting work.
Jack up the front of the vehicle and secure it on jack stands.

2. Inspect and Replace Wheel Speed Sensor

Remove the wheel:
- Use a lug wrench to loosen and remove the lug nuts.
- Remove the wheel and set it aside.
Remove the wheel speed sensor:
- Locate the left front wheel speed sensor, typically mounted near the wheel hub.
- Use a socket set to remove the mounting bolt(s) holding the sensor in place.
- Carefully disconnect the electrical connector from the sensor.
Install new wheel speed sensor:
- Position the new wheel speed sensor in place.
- Reconnect the electrical connector and secure the sensor with the mounting bolt(s).
- Torque the sensor bolt to the manufacturer's specified value (typically around 8-10 Nm).

3. Reconnect Battery and Test

Reconnect the vehicle battery.
Clear the trouble codes using the OBD-II scanner.
Perform a test drive to ensure the traction control system is functioning correctly.
