A couple codes

[d7es3l]

I have a couple of DTC's on my hands right now... P0562, P0112 and P1667

P0562 - intake air temp low voltage
P0112 - low system voltage
P1667 - CID circuit failure

What are the steps needed to fix these?
Thank you!

I just realized that the IAT is on the stock box, so I don't have to worry about that one do I? I have the 6637 in there now.

Okay I cleared the codes & then got code P1111. All good
