Abstract:
Methods and systems are provided for on-board diagnostics of an exhaust gas recirculation (EGR) system of an engine coupled to a hybrid vehicle. In one example, a method may include, upon receiving an engine shut-down request, prior to engine spin-down, rotating the engine at an idling speed via an electric motor and carrying out diagnostics of the EGR system. EGR diagnostics may include estimating a ratio of accumulated difference between a measured EGR flow and an EGR limit to accumulated intake air flow, over a duration of time, and indicating EGR system degradation in response to the ratio being higher than a threshold.

Claim (Index 8):
The method of  claim 1 , wherein the measured EGR flow is estimated via a pressure sensor coupled to a high pressure EGR line from upstream of an exhaust turbine to downstream of an intake compressor while maintaining an EGR valve coupled to the high pressure EGR line in a closed position.
