The method including operating the oil control valve responsive to cam position feedback information, the oil control valve adjusted in a first relationship based on the feedback information and operating the oil control valve in a cleaning mode during select combustion conditions by abruptly switching the oil control valve between two states responsive to the cam position feedback information. The oil control valve adjusted in a second relationship based on the feedback information, the second relationship including more abrupt adjustment than the first relationship.
