<p>Sucked air flow quantities are preliminarily alloted and stored for respective areas of predetermined ranges of the driving state of an engine, and every time a new sucked air flow quantity is detected, the stored value is renewed based on the stored value and the newly detected value. In the method and apparatus for detecting deterioration of a sucked air flow quantity-detecting device of an engine according to the present invention, the engine driving state is detected and the stored value of the sucked air flow quantity in the corresponding area is retrieved, the retrieved stored value is compared with the sucked air flow quantity actually detected by the detecting device, and deterioration is judged when the difference is larger than a predetermined value.</p> |
