Abstract
In a control system of an internal combustion engine including an intake flow control valve disposed downstream of a throttle valve, a controller controls opening and closing of the intake flow control valve, depending upon an operating state of the internal combustion engine. Upon detection of a failure in the intake flow control valve, the controller controls an intake air amount or flow rate to a different value.
