This patent describes a failure-time control device for a fuel injection controller of a internal combustion engine, which comprises in combination: (a) a trouble detecting means for detecting trouble in an intake air flow detecting means which detects a quantity of intake air flow to be introduced into an air intake passage communicatively connected with the internal combustion engine; (b) a failure-time by-pass throttle valve control means for maintaining, at a definite value on the basis of an output from the trouble detecting means, an aperture of a by-pass throttle valve which controls the quantity of air in a by-pass passage between the up-stream part and the downstream part of a main throttle valve which controls the intake air flow; and (c) a failure-time fuel injection valve control means for controlling a fuel injection quantity from a fuel injection valve supplying fuel to the internal combustion engine by injection, on the basis of a relationship of the fuel injection quantity with respect to an aperture of the main throttle valve and the number of revolutions of the internal combustion engine with the by-pass throttle valve aperture held at the definite value.
