Code C0398 2017 GMC Sierra Description
The C0398 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a Range Actuator Position - Range Position Correlation issue. This code typically points to a problem with the correlation between the range actuator position sensor and the range position sensor in the vehicle's transmission system. The range actuator is responsible for selecting the gear range in an automatic transmission, while the range position sensor detects the actual gear position selected by the actuator. When these two components are not in sync, it can lead to various performance issues in the vehicle.
Common Causes of C0398 2017 GMC Sierra
- Faulty range actuator
- Faulty range position sensor
- Damaged wiring harness
- Internal transmission issues
- Corrosion or poor connections in the sensor circuit
Symptoms of C0398 2017 GMC Sierra
- Erratic shifting behavior
- Harsh shifting between gears
- Transmission slipping or jerking
- Inability to shift gears properly
- Vehicle going into limp mode
How to Fix C0398 2017 GMC Sierra
- Diagnose the issue by using a scan tool to retrieve the DTC and perform a visual inspection of the range actuator and position sensor.
- Test the range actuator and position sensor for proper operation using a multimeter or oscilloscope.
- Inspect the wiring harness for any damage, corrosion, or poor connections, and repair or replace as needed.
- If the range actuator or position sensor is faulty, replace the defective component with a new one.
- Clear the DTC from the vehicle's computer and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix C0398 2017 GMC Sierra
The typical repair costs for addressing a Range Actuator Position - Range Position Correlation issue can vary depending on the specific cause of the problem and the labor rates at the auto repair shop. In general, replacing a faulty range actuator or range position sensor can cost between $200 and $500 for parts, with additional labor costs ranging from $150 to $300. However, the total repair cost could be higher if there are wiring issues or internal transmission problems that need to be addressed. It is advisable to check with local auto repair shops for a more accurate estimate based on the specific circumstances of the vehicle. Labor rates at auto repair shops typically range from $80 to $150 per hour, but rates may vary based on location, vehicle make and model, and engine type.
