ABSTRACT:
A bypass path is provided parallel to an intake path portion provided with a throttle valve, and the sectional area of flow in the bypass path is controlled by a valve body displaced by a stepping motor. The step value of the stepping motor is stored in a first memory storage of an electronic control. A second memory storage can keep values irrespective of opening and closing an ignition switch and the step value is stored also in the second memory storage. Corrected step values are supplied to the first memory storage from the second memory storage, from read only memory, or from a value dependent on temperature in a manner which will not result in stalling of the engine due to momentary interruptions in the supply of electric power to the electronic control.
