Abstract
Methods and systems for operating an engine including an external exhaust gas recirculation (EGR) system are presented. In one non-limiting example, output of a differential pressure sensor and output of an intake manifold pressure sensor are used as a basis for determining whether or not EGR system degradation is present while an engine is operating at conditions other than engine idle conditions.
