An engine ECU executes a program including the steps of: determining an airflow meter as abnormal when the number of times an injector is determined as abnormal (abnormality determination count C) is greater than a threshold value C( 0 ) in all of a region where DI ratio r=100%, a region where DI ratio r=0%, and a region where 0%<DI ratio r<100%, and determining the airflow meter as normal when abnormality determination count C is smaller than the threshold value C( 0 ) at least in any one region.
