Abstract: A method of monitoring an onboard diagnostic system for a plug-in hybrid electric vehicle includes incrementing the denominator of an N/D ratio for the onboard diagnostic system only when a total time criteria, a vehicle speed criteria and an idle criteria are satisfied after an internal combustion engine of the vehicle has been fueled.
