    • A system for control of the flow rate of a fluid being supplied to an internal combustion engine. The system includes a flow rate control valve for controlling the flow rate of a fluid being supplied to the engine, a pulse motor for driving the flow rate control valve, position detecting means for detecting the position of the flow rate control valve with respect to a reference position to produce two different levels of output, depending upon a detected valve position, and an electrical circuit responsive to the output of the position detecting means to drive the pulse motor. At the start of the engine, the electrical circuit is operable to drive the pulse motor in directions as a function of the output of the position detecting means, stopping same upon a certain change in the level of the above output, which corresponds to the reference position and hence setting it to a predetermined position preset as a function of parameters of the operating condition of the engine.

    • To provide a value to be replaced for an output of a manifold pressure sensor in case of failure of the manifold pressure sensor for detecting a manifold pressure for calculating the amount of fuel injection. An abnormality determination unit outputs an abnormal signal when an output voltage of a manifold pressure sensor is not within a predetermined range. A manifold pressure estimating unit calculates an estimated manifold pressure value on the basis of the engine revolution, a throttle opening, and an atmospheric pressure. The manifold pressure estimating unit uses the estimated value as a substitute value of the output of the manifold pressure sensor and continues to control the engine when the manifold pressure sensor has failed.
