ABSTRACT:
An electronically controlled internal combustion engine provided with an accelerator position sensor wherein, in order to positively prevent violent running and make some degree of running possible, an idling switch, intermediate switch and fully opening switch issuing signals when a wiper crosses them are provided within the accelerator position sensor, in case the magnitude of the output from the accelerator position sensor when any of the above mentioned respective switches issues signal during the operation of the accelerator position sensor is not in a normal range memorized in advance, the accelerator position sensor will be judged to fail and, when the accelerator position sensor is judged to fail, signals from the accelerator position sensor will not be accepted, a desirable running state will be judged on the basis of a combination of the signals from the respective switched and an injector will be controlled.
