What year ?

I recently installed a CAI kit on my V10 - there was a provision for a seperate IAT, but on my V10, there isn't one.

I believe the intake air temp is done with the MAF on my '01.

But if there's a seperate IAT for your year, it would be in the air box, or just after it in the intake tube.

That code you posted means "intake temp high" - meaning the sensor isn't necessarily bad (code would say "circuit" in it), just that the air intake temp is reading too high.

Might have a dirty MAF if it's reading it off the MAF.
