A camshaft actuator solenoid is normally installed in the front of each cylinder head. It is used to precisely control the flow of oil into the camshaft actuator. This changes the rotation of the camshaft to adjust valve timing and valve overlap on the go. These solenoids are used to control both exhaust and intake camshafts, this precise control allows to squeeze more power and fuel economy out of the engine while maintaining strict emissions standards.
