Code C1279 Lincoln Description
The C1279 diagnostic trouble code (DTC) for Lincoln vehicles specifically points to a Yaw Rate Sensor Circuit Failure. The yaw rate sensor is a crucial component of the vehicle's stability control system, also known as the electronic stability control (ESC) system. This sensor measures the rate of rotation around the vehicle's vertical axis, helping the ESC system to detect and correct any potential oversteer or understeer conditions.
Common Causes of C1279 Lincoln
- Faulty yaw rate sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or contamination affecting the sensor's readings
- Electronic control unit (ECU) communication issues
- Impact or physical damage to the sensor or its mounting location
Symptoms of C1279 Lincoln
- Illuminated ESC or traction control warning light on the dashboard
- Loss of stability control during cornering or sudden maneuvers
- Increased tendency for the vehicle to skid or slide during turns
- Reduced responsiveness of the ESC system
- ABS system may also be affected, leading to potential brake performance issues
How to Fix C1279 Lincoln
- Diagnose the specific cause of the yaw rate sensor circuit failure using a diagnostic scanner and relevant service manual procedures.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion.
- Replace the faulty yaw rate sensor if necessary, ensuring proper installation and calibration.
- Clear the DTC from the vehicle's memory using the diagnostic scanner.
- Test drive the vehicle to verify that the ESC system is functioning correctly and that the warning light is no longer illuminated.
Cost to Fix C1279 Lincoln
