What is C0849?
DTC C0849 pertains to a malfunction in the power steering system, specifically indicating a failure in the Steering Angle Sensor (SAS) or its circuit. When this code is triggered, it signifies that the vehicle’s onboard diagnostic system has detected an abnormal signal from the SAS. The steering angle sensor is crucial for various vehicle functions, including electronic stability control and traction control. A malfunction can lead to issues like loss of steering assist, which can affect the handling and safety of the vehicle. In practical terms, this means that drivers may experience a warning light on the dashboard, and in some cases, the vehicle may enter 'limp mode' to prioritize safety by limiting engine power. It's important to address this issue promptly, as ignoring it can lead to more severe problems, impacting overall vehicle performance and safety.
