I've looked on the radiator but couldn't find it. I was told that it might be inside the dash also, but i didn't want to tear it apart until I knew for sure.
where is the ambient air sensor located? on 2006 GMC Canyon
Ambient temp sensor..outside!! It's got to be in the front of the truck somewhere....but i cant tell you exactly where, sorry.
Look around inside grill area and up behind bumper covers
