SOLUTION: The voltage of a heating current applying section or the duty of pulse-width modulation for controlling the temperature of a heater to detect a breakdown and failures in normal operation are detected, and then the method decides as the breakdown when a maximum or a minimum value lasts for a fixed time or longer. the method detects whether detected signals from an air flowrate converting circuit are within a specified value to decide the presence of the failures or to self-calibrate, in a state that the operation of a constant temperature control circuit for controlling the heating temperature of the heater is stopped. A heater resistor for self-diagnostics is added near the temperature difference detecting resistor of the air flowrate converting circuit, and then the presence of failures is diagnosed by the difference between detected signals at the on-off action of the heater.
