What is B066F?

The DTC code B066F refers to a specific issue within the body control module (BCM) related to the steering wheel position sensor or the steering column. This code typically indicates that the vehicle's system has detected an abnormal signal or malfunction in the steering column's position sensor. This sensor plays a crucial role in various vehicle functions, including the electronic stability control and advanced driver assistance systems. If the B066F code is triggered, it can lead to various symptoms, including a malfunctioning steering wheel or issues with the vehicle's electronic systems. Car owners may notice that their steering feels different or that warning lights illuminate on the dashboard. Ignoring this code can lead to safety risks, as proper steering control is essential for vehicle stability. Additionally, it may affect performance features like lane-keeping assist or adaptive cruise control, which rely on accurate steering data. For drivers of certain models, such as the 2015-2020 Ford F-150 and other Ford vehicles, understanding this code is crucial for maintaining vehicle safety and functionality. If you see this code, it's advisable to address it promptly to ensure your vehicle operates as intended.
