Drive it 50-60 miles, code came back.
Question: if the valve rattles freely shouldn’t it function? Does it pull a vaccum and the split hose be the culprit? Anything else?
Thanks.

I had a problem with my ICV throwing codes a couple years ago. I pulled it and it rattled fine. I cleaned it thoroughly and put it back it. Just like you, it was ok for awhile then started throwing codes. I replaced it with a new one and haven't had the problem since. Probably something to do with the internal electrics.
