Code C1250 2017 GMC Sierra Description
The C1250 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the lateral acceleration sensor circuit registering high voltage. The lateral acceleration sensor is a crucial component of the vehicle's stability control system, which helps to maintain control during cornering and sudden maneuvers by detecting the vehicle's lateral (side-to-side) movements. When the sensor detects high voltage in its circuit, it means that there is an issue with the sensor's ability to accurately measure lateral acceleration, which can compromise the vehicle's stability and safety.
Common Causes of C1250 2017 GMC Sierra
- Faulty lateral acceleration sensor.
- Damaged wiring or connectors in the sensor circuit.
- Corrosion or contamination in the sensor connections.
- Incorrect sensor calibration.
- Communication issues between the sensor and the ECU.
Symptoms of C1250 2017 GMC Sierra
- Illumination of the stability control or traction control warning light on the dashboard.
- Increased body roll or instability during cornering.
- Unexpected activation of the stability control system during normal driving.
- Loss of traction or grip on slippery surfaces.
- Harsh or erratic braking behavior.
How to Fix C1250 2017 GMC Sierra
- Begin by conducting a thorough inspection of the lateral acceleration sensor, wiring, and connectors for any visible damage, corrosion, or loose connections.
- Test the sensor's output voltage and compare it to the manufacturer's specifications to determine if it is functioning correctly.
- If the sensor is faulty, replace it with a new one and ensure proper calibration according to the manufacturer's guidelines.
- Clear the DTC from the vehicle's ECU using a diagnostic scan tool and perform a test drive to verify that the issue has been resolved.
- If the problem persists, further diagnostics may be necessary to identify any underlying issues with the stability control system.
Cost to Fix C1250 2017 GMC Sierra
The typical repair costs for addressing a lateral acceleration sensor circuit high voltage issue can vary depending on the specific cause of the problem and the cost of parts and labor. In general, replacing a faulty lateral acceleration sensor can range from $150 to $300, while the cost of labor for diagnosis and repair can add an additional $100 to $200. Overall, the total repair cost for this issue may fall within the range of $250 to $500. However, it is important to note that these are rough estimates, and actual costs may vary based on factors such as location, vehicle make and model, and the rates charged by individual auto repair shops. It is recommended to obtain quotes from local shops to get a more accurate estimate of the repair costs.
