Code C0245 Description

The C0245 diagnostic trouble code (DTC) indicates a Wheel Speed Sensor Frequency Malfunction. This code is typically associated with the Anti-Lock Braking System (ABS) in a vehicle. The 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 to function properly and prevent wheel lock-up during braking.

C0245 Code - Wheel Speed Sensor Frequency Malfunction

Common Causes of C0245

  1. Faulty wheel speed sensor
  2. Damaged or corroded sensor wiring or connectors
  3. Poor wheel bearing condition affecting sensor signal
  4. ABS control module malfunction
  5. Electrical issues such as a blown fuse or relay related to the ABS system

Symptoms of C0245

  1. ABS warning light illuminated on the dashboard
  2. Traction control system (TCS) warning light activated
  3. Increased stopping distance during braking
  4. ABS system engaging unexpectedly or not engaging when needed
  5. Vehicle stability issues, especially during slippery road conditions

How to Fix C0245

  1. Begin by diagnosing the specific wheel speed sensor causing the issue using a scan tool to retrieve the ABS module codes.
  2. Inspect the sensor, wiring, and connectors for any visible damage or corrosion. Replace any faulty components as necessary.
  3. Test the wheel speed sensor using a multimeter to check for proper resistance and signal output.
  4. If the sensor is functioning correctly, the issue may lie with the ABS control module. Consider replacing or reprogramming the module if needed.
  5. Clear the DTCs from the ABS system using the scan tool and perform a road test to verify that the issue has been resolved.

Cost to Fix C0245

The cost of repairing a Wheel Speed Sensor Frequency Malfunction can vary depending on the specific cause of the issue and the vehicle's make and model. On average, the cost of replacing a wheel speed sensor ranges from $100 to $300, including parts and labor. If the problem is related to the ABS control module, the cost can increase significantly, potentially reaching up to $1000 or more. It's important to factor in diagnostic time and labor rates, which can vary between $80 and $150 per hour. For a more accurate estimate, it's recommended to consult with a local auto repair shop.
