ABSTRACT:
In an electronically controlled fuel injection apparatus which is controlled in accordance with the signal from a sensor for providing a signal concerning the operational condition of the associated engine, there are provided a generator for generating a stand-by signal by which the apparatus is able to continue the control operation thereof without the normal output signal from the sensor and a switching circuit for applying the stand-by signal instead of the signal from the sensor to a control section for electronically controlling the apparatus in response to detecting the occurrence of trouble in the sensor.
