Code C0287 2017 GMC Sierra Description
The C0287 diagnostic trouble code (DTC) for a 2017 GMC Sierra relates to the Longitudinal Acceleration Sensor Signal. This code indicates that there is a problem with the sensor responsible for measuring the vehicle's longitudinal acceleration, which is the acceleration or deceleration along the vehicle's lengthwise axis. The sensor is a crucial component of the vehicle's stability control system, as it provides data to help the system determine the vehicle's dynamic behavior and make adjustments to ensure optimal handling and safety.
Common Causes of C0287 2017 GMC Sierra
- Faulty longitudinal acceleration sensor.
- Wiring or connection issues affecting the sensor's signal.
- Software glitches in the stability control system.
- Malfunctioning related sensors impacting the longitudinal acceleration sensor's performance.
- Physical damage to the sensor due to impact or corrosion.
Symptoms of C0287 2017 GMC Sierra
- Illuminated stability control warning light on the dashboard.
- Decreased traction and stability, especially during acceleration or deceleration.
- Unusual or erratic behavior in the vehicle's stability control system.
- Difficulty maintaining control of the vehicle in slippery or challenging road conditions.
- ABS (Anti-lock Braking System) engaging unexpectedly or inconsistently.
How to Fix C0287 2017 GMC Sierra
- Diagnose the specific cause of the Longitudinal Acceleration Sensor Signal issue using a professional diagnostic tool.
- Inspect the sensor, wiring, and connections for any visible damage or corrosion.
- Replace the faulty sensor if necessary and ensure proper installation and calibration.
- Check and reset the stability control system to clear the DTC and test the vehicle's performance.
- Conduct a road test to verify that the issue has been resolved and that the stability control system functions correctly.
Cost to Fix C0287 2017 GMC Sierra
The typical repair costs for addressing a Longitudinal Acceleration Sensor Signal issue can vary depending on the specific cause of the problem and the labor rates in your area. Generally, replacing a faulty sensor and addressing related wiring or connection issues can range from $200 to $500, including parts and labor. However, it's essential to consider that diagnostic time and labor rates at auto repair shops can vary significantly. It's advisable to contact local auto repair shops for more precise estimates based on your vehicle make and model, as well as the severity of the issue. Keep in mind that rates at dealerships or in metropolitan areas may be higher, while independent shops often offer more competitive pricing.
