PURPOSE:To correct an erroneous output and to ensure the normal operation of a combustion device by correcting the output of oxygen concentration to a preset output value when the output is deviated from a specified range. CONSTITUTION:When the output of the oxygen concentration of an oxygen sensor is deviated from a specified range, it is determined that the combustion exhaust gas is located in a low oxygen-concentration region with incomplete combustion. The above described oxygen-concentration output is corrected to a preset output value. The erroneous output of the sensor is prevented by this correction, and the normal operation of the combustion device is not impaired. |
