Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Remove the Wheel

Using a jack, lift the front left side of the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the front left wheel.

3. Replace Wheel Speed Sensor

Locate the wheel speed sensor on the front left hub assembly.
Disconnect the electrical connector from the sensor by pressing the release tab and pulling it away.
Remove the retaining bolt(s) using a socket set and carefully extract the old sensor from its mounting hole.
Install the new wheel speed sensor into the mounting hole and secure it with the retaining bolt(s) to the specified torque (typically around 8-10 Nm).
Reconnect the electrical connector to the new sensor.

4. Reassemble Components

Reinstall the front left wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use a torque wrench to tighten the lug nuts to the manufacturer's specified torque settings (usually around 120 Nm).

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the engine and check for error codes using the OBD-II scanner to ensure C0050 has been cleared.
Perform a test drive to confirm proper operation of the ABS and traction control systems.
