Solution

1. Preparation

Gather necessary tools and ensure the vehicle is on a flat surface.
Disconnect the battery to prevent any electrical shorts.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
If necessary, remove the sensor from its mounting (usually involves unscrewing a bolt).
Clean the sensor using brake cleaner and let it dry before reinstallation.

3. Check Wiring and Connections

Examine the wiring harness leading to the wheel speed sensor for any frays or breaks.
Clean any corrosion from the connectors using electrical contact cleaner.
Ensure all connections are secure and free from moisture.

4. Replace Wheel Speed Sensor (if defective)

If the sensor shows resistance outside the specified range, replacement is necessary.
Remove the faulty sensor by unbolting it and disconnecting the wiring harness.
Install the new sensor by reversing the removal process, ensuring it fits securely.
Torque the mounting bolt to manufacturer specifications.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals, ensuring a tight fit.
Use the OBD-II scanner to clear the C0050 code and any other related codes.
Tools Required: Torque wrench.
