HELP please.

I just installed an AEM brute Force intake on my truck today (signature). 2003 Cummins 2500.

It's about 60 degrees (F) in the shop where my truck is. After installing the AEM intake, when I first turn on the key the IAT reading on the smarty touch is over 86 (note: engine was completely cool). Then, as soon as I start the truck the IAT temps climb very quickly (at idle, hood open) and a check-engine light comes on once it get around 105 or so. I get P0073 (Ambient temp sensor circuit high) and P0107 (MAP sensor circuit low) after the check engine light comes on

All the wiring looks good, everything was running fine with the factory intake installed. I have no idea why it is all of a sudden thinking it is way too hot outside.

Also, I complete took the IAT sensor (the one in the air-intake tube pre-turbo) out of the intake tube, still connected to the wiring harness but open to outside air.... and the results were the same; for some reason it thinks the temperature is a lot hotter than it actually is.

I have 2 of these sensors, tried them both and the same issue with both sensors.

I'm at my wit's end. I did nothing to any of the sensors.

Any help is appreciated
