OBD-II trouble code
U0428: Invalid Data Received from Steering Angle Sensor Module
A module is still hearing from the steering angle sensor, but the steering-position data is implausible or out of range. The link is alive — the content is wrong. Often an uncalibrated or failing sensor, or a network issue corrupting the data. Stability and steering-assist features may disable themselves.

What does U0428 mean?
U0428 is an 'invalid data' code rather than a 'lost communication' code. A module — typically the stability control (ESC/ABS) module — is still hearing from the steering angle sensor, so the connection is alive. The problem is the content: the reported steering position is out of range, implausible, or contradicts other inputs such as yaw rate and wheel speeds. The sensor is talking, but what it's saying doesn't make sense, so the receiving module rejects the data and stores U0428.
The steering angle sensor tells the stability control system where the driver is pointing the wheels, and that signal must agree with the vehicle's actual motion. The single most common cause of invalid steering-angle data is that the sensor is not calibrated (zeroed) — this is required after a battery disconnect, an alignment, steering or suspension work, or sensor replacement, and a sensor that has lost its zero point reports an angle that doesn't match straight-ahead driving. Beyond calibration, the sensor itself can fail or drift, its connector can corrode, or the clockspring/wiring in the steering column can be damaged. The usual network issues also apply: low system voltage, electrical noise, a marginal bus, or poor connections can corrupt otherwise-good messages.
Because stability and steering systems need to trust the steering angle, the typical result is that electronic stability control, traction control, lane-keeping, and sometimes electric power steering assist disable themselves and light their warning lamps until the data is valid again. The car still drives and steers mechanically, but you lose those safety aids, so U0428 should be diagnosed promptly — often the fix is as simple as performing the steering angle calibration with a scan tool.
Common causes
- Steering angle sensor not calibrated/zeroed (after battery disconnect, alignment, or steering work)
- Failing or drifting steering angle sensor
- Accompanying chassis fault producing the invalid value
- Corroded or loose steering angle sensor connector
- Damaged clockspring or column wiring
- Low system voltage causing implausible data
- Electrical noise or a marginal bus corrupting messages
- Sensor replaced without performing the required calibration
Symptoms
- Stability control (ESC) and traction control warning lights on
- Steering-assist or lane-keeping features disabled
- ABS warning light may also be on
- Power steering assist reduced or inconsistent on some vehicles
- Multiple related chassis/network codes stored alongside U0428
- Symptoms often appear right after a battery service or alignment
- Car still steers and drives mechanically
Diagnostic steps
- 1.Read ALL stored codes first — U0428 often accompanies chassis codes that name the issue.
- 2.Perform the steering angle sensor calibration with a scan tool; an uncalibrated sensor is the most common cause.
- 3.Check system voltage and the battery/charging system; low voltage can cause implausible data.
- 4.Inspect the steering angle sensor connector, clockspring, and column wiring for damage or corrosion.
- 5.Use live data to compare reported steering angle against actual wheel position while turning.
- 6.If calibration won't hold and wiring is good, the sensor or clockspring is the likely failure.
Repair cost
$80 – $700
Often the cheapest case: a steering angle calibration is roughly $80-$200 at a shop and may be the entire fix. Wiring, clockspring, or connector repair runs $150-$500. Steering angle sensor replacement plus calibration is typically $250-$700 depending on whether the sensor is a standalone unit or integrated with the clockspring. Because an uncalibrated sensor is so common, try calibration before replacing parts.

DIY vs shop
Leave this one to a qualified shop. It typically involves emissions-critical components, refrigerant handling, or other work that requires manufacturer-grade tooling, training, or certification. DIY attempts often produce a more expensive problem than the original code.
