Code C0108 Subaru Description
The C0108 code for Subaru vehicles indicates an abnormal signal of the front ABS wheel speed sensor on the left side. The ABS (Anti-lock Braking System) is a crucial safety feature in modern vehicles that prevents the wheels from locking up during braking, maintaining traction and stability. The wheel speed sensors are responsible for measuring the rotational speed of each wheel and sending this data to the ABS control module. When the ABS control module detects an abnormal signal from the front left wheel speed sensor, it triggers the C0108 diagnostic trouble code (DTC).
Common Causes of C0108 Subaru
- Damaged front left wheel speed sensor.
- Contaminated sensor due to debris or corrosion.
- Faulty wiring harness or poor connections.
- Incorrect installation of the wheel speed sensor.
- Electronic control unit (ECU) issues.
Symptoms of C0108 Subaru
- ABS warning light illuminated on the dashboard.
- Erratic or pulsating brake pedal feel during braking.
- ABS system activation at inappropriate times (e.g., on dry roads).
- Increased stopping distances during braking.
- Traction control system malfunctions.
How to Fix C0108 Subaru
- Begin by conducting a visual inspection of the front left wheel speed sensor and its wiring harness to check for any visible damage, contamination, or loose connections.
- Use a multimeter to test the sensor's resistance and check for proper voltage output while rotating the wheel by hand.
- If the sensor is faulty, replace it with a new OEM (Original Equipment Manufacturer) part, ensuring proper installation and calibration.
- Inspect and repair any damaged wiring harness or connectors, ensuring secure connections.
- Clear the DTC and perform a road test to verify that the ABS system functions correctly.
Cost to Fix C0108 Subaru
The typical repair costs for addressing the C0108 code on a Subaru vehicle can vary depending on the specific model and year.
