Help With Codes

I can't find these codes on the posted list. Can anyone tell me what they are?
P1670 and P0541. And of course the standard P0603.
I'm sure one of them has to do with the AIH delete, but I don't know which one.
Thanks

OK, I have found so much conflicting info on the P1670 that I don't know where to start.
I know that I need to replace both batteries, ( she's an '01 with the original bats ). I will get them changed and then clear codes and see if it returns. I am pulling the turbo soon for up pipe install and WW install, so I can check the UVCH and do the .50 mod. That may also be the problem. I will also replace the IDM relay.
Any other ideas?
