Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required:
- OBD-II scanner
- Multimeter
- Socket set
- Torque wrench
- Screwdriver set
Safety Warnings:
- Disconnect the battery before working on electrical systems to prevent shorts.

2. Inspect the Wheel Speed Sensor

Locate the left front wheel speed sensor near the brake rotor.
Disconnect the electrical connector from the speed sensor.
Remove the sensor from its mounting location using the appropriate socket.

3. Test the Wheel Speed Sensor

Using a multimeter, check the resistance of the sensor terminals. Refer to the vehicle manual for the specific resistance range.
If the resistance is out of specification, replace the sensor.
While rotating the wheel, check the voltage output from the sensor with the multimeter. It should produce a varying voltage signal.

4. Replace the Wheel Speed Sensor (if necessary)

If the sensor is faulty, install a new wheel speed sensor by reversing the removal steps.
Ensure the sensor is seated correctly and reconnect the electrical connector securely.

5. Reassemble and Test

Reconnect the battery and ensure all tools are removed from the engine bay.
Start the vehicle and perform a test drive to verify functionality.
Clear the error codes with the OBD-II scanner and monitor for any reoccurrence of the C0035 code.
