Code C1279 Mercury Description
The C1279 code for Mercury vehicles indicates a yaw rate sensor circuit failure. The yaw rate sensor is a crucial component of the vehicle's stability control system, as it measures the rate of rotation around the vertical axis (yaw) of the vehicle. This sensor provides vital data to the vehicle's electronic stability control (ESC) system, helping to prevent skidding and loss of control during sudden maneuvers or slippery road conditions.
Common Causes of C1279 Mercury
- Faulty yaw rate sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or moisture intrusion in the sensor components
- Electronic control unit (ECU) issues affecting sensor communication
Symptoms of C1279 Mercury
- ESC warning light illuminated on the dashboard
- Loss of stability control during cornering or sudden maneuvers
- Traction control system engaging erratically
- Increased risk of skidding or loss of control on slippery surfaces
How to Fix C1279 Mercury
- Diagnose the specific cause of the circuit failure using a diagnostic scanner
- Inspect the sensor wiring and connectors for damage or corrosion
- Test the sensor's functionality and replace if necessary
- Clear the error codes and perform a road test to ensure the issue is resolved
Cost to Fix C1279 Mercury
The typical repair costs for addressing a yaw rate sensor circuit failure can range from $200 to $500, including parts and labor. However, it's essential to note that the actual costs may vary depending on the specific vehicle model, location, and shop rates.
