P2229 Code. Barometric Pressure High

P2229 Code. Barometric Pressure High. Never heard of this code before, any insight on this?

Do you have any other codes in memory?
Looks like you may need a new IAT/MAP sensor, but it could be wiring or an ECM issue as well.

Are you good with a multimeter?

Well it showed three codes. CC Filter change, Generator Sense High, and Bar Press High. This call came about when my battery term was loose and I pulled it off while it was still running. I have cleared them but didnt run truck yet to see if codes come back. CC Filter was changed a few months ago.
