Code C123F Description

The C123F diagnostic trouble code (DTC) specifically relates to the Steering Angle Sensor (SAS) Comparative Performance. The SAS is a crucial component of the vehicle's Electronic Stability Control (ESC) system, which helps to maintain the vehicle's stability and prevent skidding during sudden maneuvers or slippery road conditions. The SAS measures the steering wheel angle and rate of turn, providing essential data for the ESC system to function effectively.
