ABSTRACT:
A method is disclosed for ensuring operation of a motorized throttle. The presence of an obstruction, such as ice, is detected inside the motorized throttle. The obstruction is then removed within a predetermined time to free the motorized throttle. A new closed throttle position is then recorded as a zero degree reference from which to control a throttle plate to a desired angle.
