•Unusual noise from the wheel area during braking

Diagnostic Steps

1
Scan the vehicle with an OBD-II scanner to confirm the C0035 code and check for any additional codes.
2
Visually inspect the left front wheel speed sensor and wiring for damage, corrosion, or loose connections.
3
Use a multimeter to test the resistance of the wheel speed sensor; it should typically be between 1,000 to 1,500 ohms.
4
Inspect the ABS module for any signs of faults or damage.
5
Check the continuity of the sensor wiring from the wheel sensor connector to the ABS module.
6
Test the wheel speed sensor signal using a scan tool or oscilloscope while rotating the wheel.

Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire connectors, and electrical tape.
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Remove the Wheel

Loosen the lug nuts on the left front wheel using a socket set.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Replace the Wheel Speed Sensor

Locate the left front wheel speed sensor, typically mounted on the wheel hub or brake assembly.
Disconnect the electrical connector from the wheel speed sensor.
Remove the mounting bolt(s) securing the sensor using the socket set.
Pull out the old sensor from its housing.
Install the new wheel speed sensor by reversing the removal steps:
- Insert the new sensor into its housing.
- Secure it with the mounting bolt(s) and torque to the manufacturer’s specification.
- Reconnect the electrical connector to the new sensor.

4. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value (typically 100-120 ft-lbs).

5. Clear the Codes

Reconnect the battery if disconnected.
Use the OBD-II scanner to clear the C0035 code and any other stored codes.
Start the vehicle and check if the check engine light remains off.
