Code C1245 Description
The C1245 diagnostic trouble code (DTC) indicates that there is a malfunction in the acceleration sensor output of the vehicle. The acceleration sensor is a crucial component of the vehicle's electronic stability control system, as it measures the acceleration and deceleration of the vehicle. This information is used by the system to determine how much braking force to apply to each wheel individually in order to maintain stability and control during sudden maneuvers or slippery road conditions.
Common Causes of C1245
- Faulty acceleration sensor.
- Damaged wiring or connectors in the sensor circuit.
- Issues with the electronic stability control module.
- Corrosion or contamination in the sensor connections.
- Electrical interference or signal noise affecting the sensor output.
Symptoms of C1245
- Unstable or unpredictable handling during acceleration, braking, or cornering.
- Illumination of the stability control warning light on the dashboard.
- Reduced effectiveness of the stability control system in slippery road conditions.
- Increased stopping distances and decreased braking performance.
How to Fix C1245
- Begin by diagnosing the specific cause of the acceleration sensor output malfunction using a diagnostic scan tool to retrieve the DTC and perform sensor testing.
- Inspect the wiring and connectors in the sensor circuit for any damage, corrosion, or loose connections. Repair or replace as needed.
- Check the acceleration sensor for proper operation and calibration. Replace the sensor if it is found to be faulty.
- Clear the DTC from the vehicle's memory using the diagnostic scan tool.
- Test drive the vehicle to confirm that the issue has been resolved and that the stability control system is functioning properly.
Cost to Fix C1245
The typical repair costs for addressing a C1245 code can vary depending on the specific cause of the issue and the extent of repairs needed. In general, the cost of replacing a faulty acceleration sensor and addressing related wiring or module issues can range from $200 to $500 or more. Labor rates at auto repair shops typically range from $80 to $150 per hour, so the total cost can add up quickly. It is advisable to consult with a trusted mechanic or dealership for a more accurate estimate based on the make and model of the vehicle.
