ABSTRACT:
A pulse signal output from a crank angle sensor is counted from start of an engine starting operation, and whether or not an engine rotation is started is determined at the time when the count result reaches a predetermined number. When the determination of the rotation start is made, a variable valve actuation mechanism is permitted to be driven.
