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.

Likely causes

Steering angle sensor not calibrated after replacement or alignment work
Software in the engine, brake or steering controller misjudging the sensor data
Steering angle sensor module faulty

Symptoms

  • Stability control or steering warning lamp
  • Stop-start stops the engine at the wrong moment or stays off
  • Check engine light on some vehicles
