Abstract
An electromagnetic valve used in controlling the amount of supplementary air supplied to an internal combustion engine to control the idling operation thereof is controlled by a current controller. The actual value of current flowing through the electromagnetic valve is compared with a predetermined value when a control signal, which is applied to the controller to regulate the opening of the electromagnetic valve, and the actual value of the current do not exhibit a predetermined correlation. It is determined whether an abnormality in the current controller is a disconnection or a short circuit based on whether the actual value of the current is greater than the predetermined value.
