Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, wrenches), torque wrench, wheel chocks.
Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Replace Wheel Speed Sensor

Sub-steps:
1. Lift the Vehicle: Raise the front of the vehicle using a jack and secure it on jack stands.
2. Remove Wheel: Take off the front left wheel to access the wheel speed sensor.
3. Disconnect Sensor: Unplug the wheel speed sensor connector.
4. Remove Old Sensor: Unscrew the wheel speed sensor from its mounting location using the appropriate socket.
5. Install New Sensor: Place the new wheel speed sensor into its mounting location and secure it with the bolt. Ensure it is properly seated.
6. Reconnect Connector: Plug the sensor connector back in, ensuring a secure fit.
7. Reinstall Wheel: Put the wheel back on, hand-tighten the lug nuts, and lower the vehicle.
8. Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the vehicle manufacturer’s specifications.

3. Clear Codes

After the replacement, use the OBD-II scanner to clear the C0010 code from the vehicle's computer.
