Code U0428 Ford Description

When the U0428 Ford diagnostic trouble code appears, it indicates that the vehicle's Engine Control Module (ECM) has received invalid data from the Steering Angle Sensor Module. The steering angle sensor is a critical component that provides the ECM with information about the position of the steering wheel. This data is essential for various safety systems, such as stability control and traction control, to function properly. When the ECM receives incorrect or inconsistent data from the steering angle sensor module, it can lead to malfunctions in these systems, compromising the vehicle's performance and safety.
