PROBLEM TO BE SOLVED: To provide an evaporated fuel processing device that even when excessive oil is supplied, can determine at appropriate timing whether or not there is an abnormality in function of a signal output section that outputs a signal about opening of an open/close member covering an oil filler port of a fuel tank, without erroneously determining.SOLUTION: An evaporated fuel processing device 11 comprises: a fuel lid for covering an oil filler port of a fuel tank; a lid switch 31 for outputting a signal about opening of the fuel lid; a fuel injection quantity integrated value memory section 71 for memorizing a fuel injection quantity integrated value that is an integrated value of values equivalent to a fuel injection quantity; a fuel injection quantity integrated value reset section 64 that resets the fuel injection quantity integrated value in response to reception of the signal from the lid switch 31; and an abnormality determination section 66 that when the fuel injection quantity integrated value reaches a preset estimation standard value, determines that there is abnormality in function of the lid switch 31. The estimation standard value is set to be bigger than a value equivalent to oil supply quantity on one occasion by a user who supplies excessive oil. |
