how to diagnose a C0019 error code on my Volvo XC60 First Generation (2008-2017)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Remove the Left Front Wheel

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

3. Inspect and Replace the Wheel Speed Sensor

• Locate the left front wheel speed sensor mounted on the wheel hub.
• Disconnect the electrical connector from the sensor.
• Remove the bolt securing the sensor to the wheel hub using a socket wrench.
• Carefully pull the sensor out of its housing, taking care not to damage the tone ring.
• Clean the sensor housing area to remove any debris before installing the new sensor.
• Install the new wheel speed sensor by reversing the removal steps and torque the bolt to the manufacturer’s specifications (typically around 8-10 Nm).

4. Reconnect Electrical Components

• Reconnect the electrical connector to the new wheel speed sensor.
• Ensure all wiring is secured and free from pinching or abrasion.

5. Reinstall the Wheel

• Place the left front wheel back onto the hub.
• Hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 120 Nm).

6. Reconnect the Battery and Clear Codes

• Reconnect the vehicle battery.
• Use the OBD-II scanner to clear the C0019 error code and any other related codes.
