Code C0108 Description
The C0108 code indicates that there is an abnormal signal coming from the front ABS wheel speed sensor on the left side of the vehicle. The ABS (anti-lock braking system) wheel speed sensors are responsible for monitoring the speed of each wheel and sending this information to the ABS control module. This data is crucial for the ABS system to function properly and prevent wheel lock-up during braking. When the sensor on the front left wheel generates an abnormal signal, it can lead to issues with the ABS system, affecting the vehicle's braking performance and overall safety.
Common Causes of C0108
- Faulty front ABS wheel speed sensor
- Damaged or corroded sensor wiring or connectors
- Debris or metallic particles interfering with the sensor's operation
- Electronic control unit (ECU) malfunction or communication issues
- Wheel bearing or hub assembly issues affecting sensor operation
Symptoms of C0108
- Illumination of the ABS warning light on the dashboard
- Loss of ABS functionality, resulting in longer stopping distances during emergency braking
- Traction control system (TCS) or stability control system (ESC) may be affected
- Uneven braking or pulling to one side during braking
- Increased wheel skidding or lock-up under heavy braking
How to Fix C0108
- Begin by visually inspecting the front left ABS wheel speed sensor and its wiring for any visible damage or corrosion.
- Use a multimeter to test the sensor's resistance and voltage output to determine if it is functioning within specifications.
- Clean the sensor and its mounting area to remove any debris or metallic particles that may be affecting its operation.
- If the sensor is faulty, replace it with a new OEM or aftermarket unit, ensuring proper installation and calibration.
- Clear the fault codes from the vehicle's ECU using a diagnostic scan tool and perform a road test to verify that the issue has been resolved.
Cost to Fix C0108
The cost of repairing an abnormal signal from the front ABS wheel speed sensor left can vary depending on the specific cause of the issue and the vehicle make and model. On average, the parts for a new ABS wheel speed sensor can range from $50 to $200, with additional costs for labor ranging from $100 to $300. Overall, the total repair cost for this issue could range from $150 to $500. It's important to note that diagnostic time and labor rates can vary between auto repair shops, so it's recommended to obtain quotes from multiple sources to get an accurate estimate for your specific situation.
