flapper valve check

Is there a way to check if the flapper valve is still working?

The flapper valve itself, or the solenoid?
The flapper valve actuator uses a diaphragm to operate the mechanism.
Something that can pull a low pressure could be attached to the hose to test the mechanism.

The system uses a hose from the throttle body (via a check valve) to apply a low pressure in a storage tank, which is then applied to the diaphragm of the flapper actuator when the flapper solenoid is energized.
