ABSTRACT:
An apparatus responsive to a change in the position of an accelerator pedal for controlling movement of a throttle valve situated within an induction passage. The induction passage has an auxiliary passage bypassing the throttle valve. A control valve is situated for movement within the auxiliary passage for controlling air flow through the auxiliary passage. The apparatus includes a control circuit which forces the throttle valve to move to its closed position and at the same time moves the control valve to permit air flow through the auxiliary passage when a failure occurs in the operation of the control circuit.
