Abstract: An apparatus for detecting an abnormality in an exhaust gas recirculation control system of an engine is disclosed, which abnormality is brought about by an operation lag of a diaphragm constituting an exhaust gas recirculation valve. The exhaust gas recirculation valve is controlled in dependence on engine operation information including an intake manifold pressure. Condition to be satisfied for enabling the abnormality decision is detected. Upon satisfaction of the abnormality decision enabling condition, the exhaust gas recirculation valve is forcibly opened and/or closed. On the basis of difference of the intake manifold pressures detected upon enforcive opening/closing of the exhaust gas recirculation valve, possible abnormality of the exhaust gas recirculation control system is decided. A temporal period during which the exhaust gas recirculation valve remains opened after the start of the engine is measured to be subsequently compared with a predetermined reference duration.
