STATE DETERMINATION DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

An engine ECU executes a program including the steps of: determining an airflow meter as abnormal (S204) 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% (YES at S202), and determining the airflow meter as normal (S206) when abnormality determination count C is smaller than the threshold value C(0) at least in any one region (NO at S202).
