Abstract
To enable early detection of abnormal states including accumulation on a pressure sensor, a characteristic measuring portion obtains a change in an output of a pressure sensor in a state in which the temperature of a sensor chip is changed by operation of a temperature controlling portion and thereby obtains a sensor characteristic indicating the change in the output. A state determination portion determines an abnormal state of a diaphragm by comparing the sensor characteristic obtained by the characteristic measuring portion with a reference characteristic, used as a reference, stored in a reference value storing portion.
