As far as I know the valves only close when the engine is on. Everything I've seen so far suggests that your large valve is fine but it's hard to say for sure without testing it with INPA.

2AAC is specific to the small DISA valve because "variable intake system 2" is the small DISA circuit. If you search around you'll find others with the same fault code and replacing the small DISA was the only fix.
