A steering angle sensor (SAS) is a device that measures the angle of the steering wheel and provides this information to the vehicle’s electronic control unit (ECU). The ECU uses this information to control various systems, such as the stability control system and the anti-lock brake system. Over time, the SAS can become misaligned, which can lead to problems with these systems. Calibrating the SAS is a procedure that corrects this misalignment and ensures that the SAS is providing accurate information to the ECU.
Calibrating the SAS is important for maintaining the safety and performance of your vehicle. If the SAS is not calibrated properly, it can lead to problems such as:
