I remote started the 06 2500 ctd at 20F outside, got in after 15min and realized I had a check engine light on.

Its for "P0111 - Intake air temperature sensor 1 Circuit Range / Performance".

I reset the codes and driven three times. Code has not returned.

The only thing i run dif on the truck is that it idles at 1500rpm to warm quicker, but other than that, its stock. Edge is dangling unhooked atm.

Any fun ideas?

Was the outside ambient temp during that remote start colder than it is on the subsequent starts? It might be that the map sensor is failing under colder temps and you just happened to catch it during the remote start event.
