The cost to diagnose the U0428 Lincoln code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
The Steering Angle Sensor Module (SASM) broadcasts the absolute steering angle value to the Power Steering Control Module (PSCM) over the HS-CAN at predefined intervals during every drive cycle from the first ignition ON status. During normal operation the absolute steering angle from the SASM is compared against a steering angle derived from the rear wheel speed values broadcast by the ABS module over the HS-CAN and an angle derived from the EPAS motor position. If the absolute steering angle values and the derived steering angles do not match, the EPAS system is set to a default level of assistance. The invalid data Diagnostic Trouble Code (DTC) will be set when a receiving device detects a discrepancy in the information it receives from the Steering Angle Sensor Module causing its integrity to be questioned.
