Systems and methods for diagnosing operation of an internal exhaust gas recirculation system of an internal combustion engine are presented. The system and method may be applied to conventional or hybrid powertrains having a capability to rotate an engine via an electric machine. The internal exhaust gas recirculation system may be diagnosed based on output of a differential pressure sensor.
