Abstract: The present invention includes a sensor malfunction determination unit 207 detects the pressure value corresponding to a signal outputted by a pressure sensor 101 capable of measuring the internal pressure of a pneumatic tire 10. When the detected pressure value is decreasing along the time axis, the sensor malfunction determination unit 207 determines that the pressure sensor 101 is not malfunctioning.
