Abstract
An engine control apparatus equips with an air flow meter for generating a signal having a frequency proportional to an air flow rate for feeding into the engine. A circuit for monitoring an arithmetic and logic unit is equipped to detect a fault of the arithmetic and logic unit thereby switching a control of a fuel feed valve from the control by the arithmetic and logic unit to a monostable multivibrator so as to prevent an inoperability of driving of a car.
