Code C1254 2016 GMC Sierra Description
The C1254 diagnostic trouble code (DTC) on a 2016 GMC Sierra indicates a problem with the longitudinal acceleration sensor's performance. The longitudinal acceleration sensor is a crucial component of the vehicle's stability control system, which helps to maintain traction and stability during acceleration, braking, and cornering. This sensor measures the vehicle's acceleration in the forward and backward direction, providing data to the vehicle's electronic control unit (ECU) to make adjustments to the stability control system as needed.
Common Causes of C1254 2016 GMC Sierra
- Faulty longitudinal acceleration sensor.
- Wiring issues or poor connections in the sensor circuit.
- Corrosion or damage to the sensor or its mounting location.
- Electronic control unit (ECU) malfunction.
- Vehicle impact or collision that may have damaged the sensor or its components.
Symptoms of C1254 2016 GMC Sierra
- Illumination of the traction control or stability control warning light on the dashboard.
- Decreased traction and stability, especially during acceleration or braking.
- Increased wheel slip or skidding during driving.
- Unusual or erratic behavior of the stability control system.
- Loss of control or difficulty maintaining a straight line while driving.
How to Fix C1254 2016 GMC Sierra
- Diagnose the issue by using a scan tool to retrieve the specific DTC and perform a visual inspection of the sensor and its wiring.
- Test the longitudinal acceleration sensor using a multimeter to check for proper voltage and resistance readings.
- Replace the faulty sensor if it is determined to be the cause of the issue.
- Inspect and repair any damaged wiring or connections in the sensor circuit.
- Clear the DTC from the ECU's memory and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix C1254 2016 GMC Sierra
The typical repair costs for addressing a longitudinal acceleration sensor performance issue can vary depending on the specific cause of the problem. In general, replacing the sensor itself can range from $100 to $300, while additional costs for diagnostic time, labor, and any necessary wiring repairs can increase the total cost. Overall, the total repair cost for this issue may range from $200 to $500, but it's advisable to consult with a professional mechanic for a more accurate estimate based on the specific circumstances of the vehicle. Keep in mind that labor rates at auto repair shops can vary, so it's recommended to inquire about rates in your local area for a more precise estimate.
