U0428 Ford Code - Invalid Data Received From Steering Angle Sensor Module

Quick Answer

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. Common causes include Faulty Steering Angle Sensor Module (SASM), Steering Angle Sensor Module harness is open or shorted, Steering Angle Sensor Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U0428 Ford Description

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.

Frequently Asked Questions about U0428 Ford Code

1. What does the OBDII code U0428 mean on a Ford vehicle?

The code U0428 indicates that the vehicleâ€™s control module has received invalid or corrupted data from the steering angle sensor module.

2. What are common symptoms of the U0428 code in a Ford?

Symptoms may include the activation of the check engine light, malfunction indicator lights related to stability or traction control, and erratic steering behavior.

3. What causes the U0428 code to appear in a Ford vehicle?

Common causes include a faulty steering angle sensor, damaged wiring or connectors, software issues in the control module, or calibration errors.

4. Can I drive my Ford with the U0428 code active?

While the vehicle may still be drivable, issues with the steering angle sensor could impact safety systems like traction control or stability assist, so itâ€™s best to address the issue promptly.

5. How can I fix the U0428 code on my Ford?

Start by inspecting the wiring and connectors for damage or corrosion. If no issues are found, consider recalibrating or replacing the steering angle sensor.

6. Do I need to replace the steering angle sensor to fix U0428?

Not always. Sometimes recalibrating the sensor or repairing damaged wiring can resolve the issue without replacement.

7. Can a low battery cause the U0428 code in my Ford?

Yes, a weak or failing battery can cause communication errors between modules, potentially triggering the U0428 code.

8. How do I recalibrate the steering angle sensor in a Ford?

Recalibration typically requires a diagnostic scan tool with the proper software to reset and align the sensor values to factory settings.

9. Is the U0428 code related to the ABS or traction control system?

Yes, the steering angle sensor is a critical component for systems like ABS, traction control, and stability control, so the U0428 code can affect their functionality.

10. What happens if I ignore the U0428 code in my Ford vehicle?

Ignoring this code could lead to compromised safety system performance, including reduced traction and stability control, potentially increasing the risk of an accident.
