U0428 — Invalid Data Received From Steering Position Sensor Control Module #

DTC U0428 means that a control module has received data from the steering position or steering angle sensor control module that it considers invalid, implausible, or inconsistent.

This is an important distinction: U0428 does not automatically mean that communication with the steering sensor module has been completely lost. The module may still be online and transmitting data, but another controller does not consider that data trustworthy.

Accurate steering position information is used by systems such as ABS, electronic stability control, traction control, electric power steering, and on some vehicles driver-assistance systems. For that reason, U0428 may cause several warning lights or temporarily disable functions that depend on steering angle information.

What Does U0428 Mean? #

The steering position sensor tells vehicle control modules where the steering wheel is positioned and how it is moving. Depending on the vehicle, this information may come from a dedicated steering angle sensor, a steering column module, an electric power steering module, or another integrated controller.

When another module receives steering-position information that does not make sense compared with other vehicle data, it may store U0428.

Examples include:

• a steering angle value that is offset when the wheels are physically straight;
• a value that changes incorrectly or intermittently as the wheel is turned;
• steering-position data that does not agree with yaw-rate, wheel-speed, or vehicle-dynamics information;
• a module that has lost its steering-angle calibration;
• incorrectly coded or initialized replacement components;
• electrical or network faults corrupting the transmitted data.

Therefore, U0428 should be diagnosed as an invalid-data fault, not automatically as a failed CAN bus or failed steering sensor.

U0428 vs U0126 #

These two codes can appear similar but indicate different conditions.

• U0428: a module receives steering-position data but considers that data invalid or implausible.
• U0126: communication with the steering position sensor control module has been lost.

If the steering module is visible on the diagnostic scan and live steering-angle data is available, diagnosing U0428 as a complete communication failure can send the repair in the wrong direction.

If U0126 or several communication-related U-codes are stored at the same time, however, network integrity, power supply, grounds, and module communication become more important parts of the diagnosis.

Possible Symptoms of U0428 #

The symptoms depend on which module has rejected the steering-position data and on the vehicle’s control-system design.

• ABS warning light
• ESC or stability-control warning
• traction-control warning
• steering or power-steering warning message
• stability-control functions temporarily disabled
• reduced or altered electric steering assistance on some vehicles
• lane-keeping or other driver-assistance functions unavailable on equipped vehicles
• no noticeable driving symptom other than warning lights

U0428 itself does not prove that the steering mechanism has a mechanical fault.

Possible Causes of U0428 #

There is no single cause that applies to every vehicle. The fault should be diagnosed from the accompanying codes, live data, recent repair history, and the manufacturer’s procedures.

• steering angle or steering position sensor calibration lost or incorrect;
• sensor value offset after steering, suspension, wheel-alignment, or steering-column work;
• faulty steering angle or steering position sensor;
• fault inside the steering column or steering control module;
• incorrect module coding, initialization, or programming after replacement;
• low system voltage or unstable module power supply;
• poor ground connection;
• damaged, loose, contaminated, or corroded connectors;
• damaged wiring;
• CAN network fault when other communication symptoms are also present;
• incorrect data interpretation by another module because of a separate fault or software issue.

Check Recent Repairs First #

Before testing components, determine whether U0428 appeared after any work involving:

• wheel alignment;
• steering rack replacement;
• steering column work;
• steering wheel removal;
• steering angle sensor replacement;
• ABS or stability-control repairs;
• suspension work;
• module replacement or programming;
• battery or charging-system problems.

On vehicles that require steering-angle initialization, a component can be electrically functional while still transmitting a value that other modules consider implausible.

How to Diagnose U0428 #

1. Perform a complete vehicle scan #

Do not diagnose U0428 from the engine ECU alone. Scan every available module and record all stored, pending, history, and communication codes before clearing anything.

Pay particular attention to faults stored in ABS/ESC, electric power steering, steering column, body, gateway, and driver-assistance modules.

2. Identify which module stored U0428 #

U0428 tells you that one controller rejected data originating from the steering-position system. Knowing which controller stored the fault helps determine which systems were comparing or using that information.

3. Check steering-angle live data #

With the vehicle stationary and the wheels positioned straight ahead, display the steering-angle or steering-position parameter on a capable diagnostic tool.

Then slowly turn the steering wheel left and right while watching the value.

The exact values and allowable tolerances are manufacturer-specific, but the reading should generally:

• change smoothly;
• change in the correct direction;
• avoid sudden jumps or dropouts;
• remain available throughout steering movement;
• be reasonably consistent with the physical steering-wheel position.

If the wheels are straight but the reported steering angle is substantially offset, calibration or mechanical alignment should be investigated before replacing the sensor.

4. Look for calibration or initialization requirements #

Many vehicles require a steering-angle calibration, zero-point reset, initialization, or relearn after certain repairs.

Use the manufacturer-specific procedure whenever available. Do not assume that simply clearing U0428 will recalibrate the system.

5. Check power, grounds, and connectors #

If the sensor value is intermittent or the module occasionally disappears from the scan, inspect its electrical supply before condemning the sensor.

Check:

• battery and charging voltage;
• module power supplies;
• ground voltage drop;
• connector pin fit;
• corrosion or moisture;
• wiring damage near the steering column, rack, or module.

6. Investigate the CAN network only when evidence points there #

A CAN-bus diagnosis is appropriate when U0428 is accompanied by symptoms such as:

• multiple U-codes across several modules;
• intermittent loss of communication with the steering module;
• U0126;
• modules repeatedly appearing and disappearing from the scan;
• confirmed network-voltage or waveform abnormalities.

If the steering module communicates normally and its live data is present, do not begin by assuming that the entire CAN network is defective.

7. Compare related vehicle-dynamics data #

On an advanced scan tool, compare steering-angle information with other available parameters such as wheel speeds, yaw rate, or steering torque.

The goal is not to find one universal numerical specification, but to identify information that is clearly inconsistent with the actual vehicle state.

8. Clear the fault only after diagnosis or repair #

After the root cause has been corrected, clear the codes, perform any required calibration procedure, and road-test the vehicle while monitoring the relevant parameters.

Common Repairs for U0428 #

The correct repair depends on the diagnosis. Possible repairs include:

• performing the correct steering-angle calibration or zero-point procedure;
• correcting wheel alignment or steering-centering issues when applicable;
• repairing damaged wiring or connectors;
• repairing module power or ground circuits;
• replacing a confirmed faulty steering angle sensor;
• repairing or replacing a confirmed faulty steering control module;
• coding or programming a replacement module correctly;
• repairing a CAN-network fault when testing proves that one exists.

A steering angle sensor or control module should not be replaced solely because U0428 is present.

Common Diagnostic Mistakes #

• Assuming U0428 means “no communication.” The data may be present but invalid.
• Replacing the steering-angle sensor immediately. Calibration, alignment, voltage, wiring, or coding may be the actual problem.
• Ignoring recent wheel-alignment or steering repairs. These can be highly relevant to steering-angle plausibility.
• Checking only engine codes. ABS, ESC, EPS, gateway, and steering modules often provide the information needed to understand U0428.
• Clearing the code before recording other faults and live data. This can remove useful diagnostic evidence.
• Disconnecting the battery as a “repair.” A battery reset does not correct incorrect calibration, wiring damage, sensor failure, or network faults and may create additional initialization requirements on some vehicles.
• Diagnosing the CAN bus without evidence. A valid communication link can still carry implausible steering-position data.

Can You Drive With U0428? #

The answer depends on the symptoms.

If the vehicle has only a warning light and steering behavior remains completely normal, the vehicle may still be movable for diagnosis, subject to the manufacturer’s instructions.

If steering assistance becomes reduced, steering behavior is abnormal, or stability-control functions are malfunctioning, continued driving may be unsafe. The underlying fault should be diagnosed before normal use.

Can Low Battery Voltage Cause U0428? #

Low or unstable voltage can contribute to invalid module data or initialization problems, particularly if several control modules report faults at the same time.

Battery condition and charging voltage are therefore worth checking, but a low-voltage assumption should not replace diagnosis of the steering-position system.

Does a Wheel Alignment Cause U0428? #

A normal wheel alignment does not automatically create U0428. However, if steering geometry, steering-wheel position, steering components, or a sensor reference position has changed, some vehicles may require a steering-angle calibration afterward.

If U0428 appears immediately after alignment, steering-rack work, suspension work, or steering-column work, check steering-angle live data and the manufacturer’s calibration procedure.

Do You Need a Professional Diagnostic Tool? #

A basic generic OBD2 reader may display U0428 but often cannot access the ABS, ESC, EPS, steering-column, or gateway modules required for a complete diagnosis.

A multi-system diagnostic tool capable of reading all control modules, displaying steering-angle live data, and performing the appropriate calibration procedure is considerably more useful for this fault.

U0428 FAQ #

Does U0428 prove the steering angle sensor is defective? #

No. It only indicates that a module considers steering-position data invalid. Calibration, wiring, voltage, coding, network problems, or another control-system fault may produce the same code.

Will clearing U0428 fix it? #

No. Clearing the code only erases the stored fault. If the invalid data condition remains, U0428 will return.

Should I disconnect the battery? #

Battery disconnection is not a diagnostic repair for U0428. It may also require additional initialization procedures on some vehicles.

What should I check first? #

Start with a complete module scan, identify related codes, check whether the steering module communicates normally, inspect live steering-angle data, and determine whether recent steering or suspension work could have affected calibration.
