Abstract
An Exhaust Gas Recirculation (EGR) effective flow diagnosis method includes: measuring an EGR gas temperature by an EGR gas temperature sensor under an EGR gas temperature rise condition of an EGR system on an intake line; determining the degree of the EGR gas temperature rise; and determining whether an EGR effective flow is excessive or insufficient according to the degree of the EGR gas temperature rise.
