DIC Codes
I've had a check engine light twice in 3 days with the same codes, P1416HC, B0361HC, B2282H, B2284H, U1064H, B2283H, B2285H and U1064H.
All are History codes, except for P1416HC and B3061HC show as current. Any insight to what is happening would be appreciated!

The internet is your friend when you need to find out what a certain code means. My search found that p1416hc is a code for the secondary air system bank 2, this means there is something amiss with the system that helps reduce emissions, I would look over all the hoses that are part of that system. The B4061hc did not appear on any list, if you meant b0361hc that is a hvac code.

I just had the 1416 as well. (I just reset it for now to see what happens) Most likely the check valve which is a real pain to replace. There are threads about cleaning it as best as possible that works quite often. You can search for passenger side check valve I think and will find them.
There is a place where you remove the hose and spray carb or MAF cleaner in and then chase it in with air then maybe some wd40 so the check valve frees up.
Not sure about the HVAC code.

Thanks for the feedback! I'll give cleaning the check valve a shot, and see what happens. The odd thing is, the code comes up every other time I drive it.
I'll clear the code, then drive it without a problem. The next time I drive it, the check engine light comes on after 20 miles or so with the P1416 code.
