What U0428 means
U0428 is for a separately networked steering angle sensor module, usually on the column, feeding angle and rate to stability control, assistance and stop-start. GM's 2025 brake module counts wrong checksums or counters in its frames (8 of a 16 window) and reacts at once to a cleared validity bit or a data mask stuck at zero, all Type C without MIL. Where the angle comes from the steering gear, GM files a similar data mask fault under U0420. Mitsubishi's 2019 Outlander PHEV sets U0428 in the PHEV-ECU on a failed sensor signal; after the CAN check and data item 333 it asks for calibration and a steering angle offset reset. Jeep cured U0428 with MIL and early engine stops in stop-start on the 2017 Cherokee 3.2 L by PCM software (18-013-17). Audi fixes U042800 on dynamic steering by software (2049656/1). U0126 is lost contact.
U0428 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0428
- Stability control or steering warning lamp
- Stop-start stops the engine at the wrong moment or stays off
- Check engine light on some vehicles
Common causes of U0428
- Most likelySteering angle sensor not calibrated after replacement or alignment work
- PossibleSoftware in the engine, brake or steering controller misjudging the sensor data
- PossibleSteering angle sensor module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0428 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 28 | The exact fault in that area. |
What to do next
- Note U0428 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0428
What does U0428 mean?
U0428 means "Invalid Data Received From Steering Angle Sensor Module". U0428 is for a separately networked steering angle sensor module, usually on the column, feeding angle and rate to stability control, assistance and stop-start. It is a generic code, so it means the same on every make.
Is it safe to drive with U0428?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will U0428 fail an emissions test?
U0428 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0428 to fix?
Difficulty: workshop only. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will U0428 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
