Abstract
A method of controlling an engine having a valve actuation system is provided. The engine is started. A first parameter indicative of a first temperature of the engine is sensed. A second parameter indicative of a second temperature of the engine is sensed. The valve actuation system is disabled to prevent the implementation of a variation on conventional engine valve actuation timing in response to each of the first and second temperatures being below a predetermined value.
