When this sensor malfunctions or provides inaccurate data, it can lead to a range of issues that affect the vehicle's performance, safety, and overall driving experience.
Common Causes of C1A47
- Faulty steering angle sensor.
- Wiring or connection issues with the SAS.
- Software glitches or calibration errors in the ESC system.
- Physical damage to the SAS due to external factors such as water ingress or impact.
- Malfunctioning ABS module affecting the SAS readings.
Symptoms of C1A47
- Illumination of the ESC or traction control warning light on the dashboard.
- Unresponsive or jerky steering wheel movements.
- Loss of stability and traction control during sharp turns or sudden maneuvers.
- Vehicle veering to one side while driving.
- Difficulty in maintaining control of the vehicle on slippery surfaces.
