ABSTRACT:
In control apparatus for an internal combustion engine which includes a plurality of sensors for detecting parameters representing operation state of the engine to thereby output respective sensor signals, a crank angle sensor for generating a reference period signal in synchronism with rotation of the engine, a fuel injector for injecting fuel in the engine and an air-fuel ratio controller for determining a driving time of the fuel injector on the basis of one of the sensor signals and the reference period signal includes a filter for filtering the one sensor signal, a decision means for making decision as to normality or abnormality of the one sensor signal, and a means responsive to the decision of abnormality of the one sensor signal for thereby determining the driving time on the basis of another sensor signal and a means responsive to restoration of the one sensor signal to the normal state to thereby enable the determination of the injector driving time based on the one sensor signal to be resumed only after lapse of a first delay time from the restoration of the one sensor signal to the normal state. The driving time can be corrected by taking into account the temperature of the engine cooling water.
