U0126Lost Communication With Steering Angle Sensor Module
- Generic OBD-II code · Network
- Turns on the check-engine light
- How the car detects it
- U0126 means the steering wheel angle sensor, usually mounted on the steering column, is no longer heard on the bus. ESC needs this value to know the path the driver intends. Mitsubishi's 2019 Outlander PHEV sets U0126 in the PHEV-ECU when it loses its CAN link to the wheel-angle sensor and demands calibration after a sensor swap. Mercedes reports U012600 with check-engine lamp after remote start, traced to software and the column module (LI27.00-P-073106). GM PIT5755 warns that some 2020 Silverado HD brake controllers log the same fault as U0131. Saab's list uses symptom bytes 71/72/74/5A. U0428 covers invalid angle data. Expect ESC warnings, sometimes a MIL.
