Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

Tools Required: Socket set, torque wrench, multimeter, OBD-II scanner.
Sub-steps:
1. Remove the Wheel: Use a lug wrench to remove the left front wheel for better access to the wheel speed sensor.
2. Disconnect the Sensor: Locate the wheel speed sensor on the left front hub and disconnect its electrical connector.
3. Remove the Sensor: Use a socket or wrench to remove the mounting bolt(s) securing the wheel speed sensor. Carefully pull the sensor out of its mounting location.
4. Install New Sensor: Insert the new wheel speed sensor into the mounting hole and secure it with the bolt(s) to the specified torque (consult the vehicle's repair manual for the exact torque value).
5. Reconnect the Sensor: Reattach the electrical connector to the new wheel speed sensor.

3. Check Wiring and Connectors

Inspect the wiring harness for any signs of wear or damage. Repair any damaged wiring.
Ensure all connectors are clean and free of corrosion.

4. Reconnect Battery and Test

Reconnect the vehicle’s battery.
Clear the C0013 code using the OBD-II scanner.
Start the vehicle and perform a test drive to check for any reoccurrence of the code and ensure proper operation of the ABS and traction control systems.
