If an alcohol sensor which determines the amount of alcohol which is mixed with gasoline, malfunctions, the fuel supply correction factor which is designed to modify the basic fuel supply amount to compensate for the amount of alcohol, is prevented from being changed in accordance with the output of the alcohol sensor, and temporarily calibrated by feedback from the air-fuel ratio sensor disposed in the exhaust system.
