A diagnostic apparatus for gas mixture supply apparatus and diagnostic method thereof characterized in that, when any trouble has occurred to gas mixture from a gas mixture supply apparatus, it can be identified as an error; and at least engine startup is ensured, continued operation of the engine can be made enabled without any problem which may cause stalling of the engine, and deterioration of exhaust gas can be prevented. The above object can be attained by the present invention comprising a gas mixture state detecting means for detecting the state of gas mixture when gas mixture is supplied from the aforementioned gas mixture supply means during the operation of the aforementioned evaporation means, and evaluation means for evaluating an error of the aforementioned gas mixture supply means based on the result of detection by the aforementioned gas mixture state detecting means.
