An engine control method of a plug-in hybrid electric vehicle, the method comprising steps of: accumulating an electric vehicle (EV) accumulated driving distance or an EV accumulated driving time; comparing the EV accumulated driving distance with a reference driving distance or the EV accumulated driving time with a reference driving time; informing that an engine operation for inspection is necessary when the EV accumulated driving distance is greater than the reference driving distance or the EV accumulated driving time is greater than the reference driving time; and operating an engine for inspection if a signal to operate the engine for inspection is input; wherein the EV accumulated driving distance and the EV accumulated driving time are stored continuously in a memory of the vehicle and read from the memory after an ignition switch is switched on.
