Code C0245 Hummer Description
The C0245 diagnostic trouble code (DTC) for Hummer vehicles indicates a Wheel Speed Sensor Frequency Malfunction. This code is typically associated with the Anti-Lock Braking System (ABS) and traction control systems. The wheel speed sensors are responsible for monitoring the speed of each wheel and sending this information to the ABS control module. When the control module detects a discrepancy in the wheel speed sensor frequency, it triggers the C0245 code.
Common Causes of C0245 Hummer
- Worn or damaged wheel speed sensors
- Corroded or loose wiring connections
- Contaminated wheel speed sensor surfaces
- Faulty ABS control module
- Electrical issues such as short circuits or open circuits
Symptoms of C0245 Hummer
- Illuminated ABS warning light on the dashboard
- Traction control system malfunction indicator
- Erratic ABS system activation during braking
- Increased stopping distances
- Loss of traction on slippery surfaces
How to Fix C0245 Hummer
- Diagnose the specific wheel speed sensor causing the frequency malfunction using a scan tool.
- Inspect the wheel speed sensor for damage, contamination, or loose connections.
- Replace the faulty wheel speed sensor if necessary.
- Clear the DTC and perform a road test to verify proper ABS and traction control system operation.
- If the issue persists, further diagnosis of the ABS control module and wiring harness may be required.
Cost to Fix C0245 Hummer
The typical repair costs for addressing a Wheel Speed Sensor Frequency Malfunction can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that diagnosis time and labor rates at auto repair shops can vary, with hourly rates typically ranging between $80 and $150. Factors such as location, vehicle make and model, and engine type can also influence repair costs. For a more accurate estimate, it is recommended to consult with a local auto repair shop.
