Code C0245 Buick Description
The C0245 Buick code indicates a Wheel Speed Sensor Frequency Malfunction. This means that the vehicle's onboard computer has detected an issue with the wheel speed sensor's signal frequency, which is crucial for the proper functioning of the vehicle's anti-lock braking system (ABS) and traction control system (TCS). The wheel speed sensors are responsible for monitoring the rotational speed of each wheel and sending this data to the ABS and TCS systems to help prevent wheel lock-up during braking and improve traction control.
Common Causes of C0245 Buick
- Faulty wheel speed sensor
- Damaged or corroded wiring connections
- Misaligned or damaged tone rings
- Issues with the ABS module or control unit
- Faulty ABS or TCS system components
Symptoms of C0245 Buick
- Illumination of the ABS or TCS warning light on the dashboard
- Erratic or inconsistent braking behavior, especially during hard stops
- Traction control system engaging unexpectedly or not working properly
- ABS system activation during normal driving conditions
- Uneven braking or pulling to one side while braking
How to Fix C0245 Buick
- Begin by diagnosing the specific wheel speed sensor that is causing the frequency malfunction using a scan tool.
- Inspect the sensor for any visible damage, corrosion, or loose connections. Replace the sensor if necessary.
- Check the wiring harness for any breaks, fraying, or corrosion. Repair or replace any damaged wiring.
- Inspect the tone rings on the wheel hubs for damage or misalignment. Adjust or replace them as needed.
- Clear the diagnostic trouble codes from the vehicle's computer and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix C0245 Buick
The typical repair costs for a Wheel Speed Sensor Frequency Malfunction can range from $100 to $300, including parts and labor.
