ABSTRACT:
A method of determining failure of sensors in a control device for an internal combustion engine which comprises steps of setting a predetermined time corresponding to a warmup time of the sensors after an electric power source is activated; determining whether the predetermined time elapses from when the electric power source is activated; determining whether output signals of the sensors are in allowable ranges when the predetermined time elapses; determining the sensors as normal when the output signals of the sensors are in the allowable ranges; and determining the sensors as abnormal when the output signals of the sensors are out of the allowable ranges.
