Code C123F Jeep Description

The C123F diagnostic trouble code (DTC) for Jeep vehicles specifically refers to an issue with the Steering Angle Sensor (SAS) comparative performance. The SAS is a crucial component of the vehicle's stability control system, as it measures the steering wheel angle and rate of turn. This information is used by the vehicle's electronic stability control (ESC) system to determine the appropriate response to sudden changes in direction or loss of traction.
