• The property of the variable tumble shutter valve switch built into the variable tumble shutter valve actuator is adjusted to reduce the effect on the switch caused by the production tolerance of the intake manifold and variable tumble shutter valve actuator.
• If the variable shutter valve actuator is removed from the intake manifold, a significant deviation to the switching performance will result.Therefore, do not remove the variable tumble shutter valve actuator from the intake manifold.
