Abstract
A tire pressure monitoring system () for a vehicle () has a pressure sensor circuit (A) that includes an ECU (), a transmitter/receiver (), and pressure sensor (). A method of operating a tire pressure monitoring system includes calibrating a tire pressure sensor circuit in a first range and a second range and generating a first calibration data for the first range and second calibration data for the second range. The first calibration data and the second calibration data are stored in a memory of the tire pressure sensing circuit (A). A data signal corresponding to the pressure is generated. The first or second calibration data is generated in response to the range of the data signal to form a selected calibration. The data signal is calibrated with the selected calibration to form a pressure indicative signal. The pressure indicative signal is transmitted to a receiver () within the vehicle () with a range status corresponding to the selected calibration. A pressure signal is formed in response to the pressure indicative signal and the range status and the tire pressure monitoring system is operated with the pressure signal.
