ABSTRACT:
When fully closed valve judging means judges that the detected throttle opening is equal to or smaller than a full close criterion value, valve moving amount judging means judges that a change in detected throttle opening per a predetermined time is equal to or smaller than a movement criterion value, and opening difference judging means judges that the difference between the detected throttle valve and the target throttle opening is equal to or larger than a difference criterion value, a car throttle controller considers that the throttle valve is fixed at a fully closed position and outputs a malfunction signal.
