This patent describes a method of controlling an operation amount of an operation control for controlling the operation of an internal combustion engine having an intake passage and an intake air quantity control means for regulating the quantity of intake air being supplied to the engine through the intake passage by adjusting the opening area of the intake passage. The operating amount of the operating control is controlled to required values dependent on operating conditions of the engine. In synchronism with generation of pulses of a predetermined control signal, the method consists of: (1) determining whether or not the engine is operating in a predetermined low load condition; (2) detecting a value of the opening area of the intake passage, when the engine is determined to be operating in the predetermined low load condition; (3) determining a desired value of the operating amount of the operation control means on the basis of the detected value of the opening area of the intake passage; (4) determining a correction value on the basis of a difference between the detected value of the opening area of the intake passage and an actual value of same; (5) correcting the desired value of the operating amount determined at the step (3) by the correction value; and (6) controlling the operating amount of the operation control means to the desired operating amount thus corrected.
