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 7):
The method of  claim 6 , further comprising, in response to the accumulated intake air flow being lower than the second threshold accumulation limit at an end of the first threshold duration, continuing each of the accumulation of the difference between the measured EGR flow and the EGR limit, and the intake air flow during an immediately subsequent period of engine rotation at the idling speed until the accumulated intake air flow reaches the second threshold accumulation limit.
