• If the actuator fully closes after each operation of the air charging system, the intake air pressure in the air charging system increases excessively, which could cause the air hose to come off, or damage the air charging system. To prevent this, if the air pressure in the air charging system exceeds a specified value, the pressure is released upstream of the turbocharger.
