U0429 Invalid Data Received from Steering Wheel Angle Sensor
The Steering Wheel Angle Sensor is present on the data bus but the values it reports are implausible — out of range, frozen, or failing the checksum or rolling-count check. The receiving modules reject the data. Stability control loses a trustworthy steering-angle value. Causes include a faulty sensor feeding the module, internal computation errors, a software or calibration mismatch after a repair, or bus interference corrupting the frames.
Is it safe to drive with U0429?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
