The Steering Angle Sensor, or the SAS, is the clockspring assembly that also provides data for the traction and stability control system. You will need to pull the steering wheel and replace it. There is a calibration procedure that is supposed to be performed by centering the SAS sensor, and turning the steering wheel 15 degrees to the left, then 15 degrees to the right , but I have replaced them without doing this and the system will figure out on it's on where the centerline is. Replace this sensor and clear the code and you should be good to go. Let me know if you have any further questions. Thank you.
