U0430 Invalid Data Received from Tire Pressure Monitoring Sensor
The Tire Pressure Monitoring 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. Tire-pressure readings become unreliable. 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.
