Abstract

The present disclosure relates to a method and a system capable of determining the cause of misfire if the misfire occurs due to the mechanical failure of an injector. The present disclosure senses whether the misfire of an engine occurs, determines whether the mechanical failure occurs in an injector of a cylinder in which the misfire occurs, if the misfire of the engine is sensed, and determines that the misfire of the engine occurs due to the injector, and stores the failure content of the injector in a maintenance code, if it is determined that the mechanical failure occurs in the injector.
