Abstract:
A control method for an internal combustion engine of a vehicle that is used with a variable valve timing (VVT) system to promote lock pin disengagement. The method establishes if the VVT is at a lock pin position, establishes if a lock pin is not disengaged out of an associated recess, and can control the rate of movement of the VVT away from the lock pin position so that the lock pin can be disengaged out of the recess.
