ABSTRACT:
An internal combustion engine control apparatus which infers opening and closing of a throttle valve upon failure of throttle detecting switch. A programmed computer calculates basic fuel injection amount in accordance with detected rotational speed and air flow and discriminates failure of the throttle detecting switch when output of the throttle detecting switch does not correspond to the calculated basic fuel injection amount and the detected rotational speed. When the computer discriminates failure of the switch, the computer infers opening and closing of the throttle valve by comparing the calculated basic fuel injection amount with a reference value indicative of normal fuel injection amount closed throttle. The reference value is a function of the rotational speed and updated by the calculated basic fuel injection amount under closed throttle condition.
