I was putting in my new billet grilles today and when doing so saw a sensor about six inches long simply laying at the bottom of the bumper, not attached to anything. It appears that it should be. It is still wired in. Just don't know what it is and where is should be mounted.

I have a pic but I do not see the manage attachments icon as noted in the faq's page?

Help with either issue?
Thanks,

 

sounds like your outside air temperature sensor to me.

 

Assuming your car has an outside temperature probe, I agree.

You can't post pics until you have something like 50 posts, I think.

 

It's here on my car:

 

PSSTTT, your grille is missing

 

It's still there. 16-gauge mesh and flows a heck of a lot better than stock which is almost entirely solid plastic and weighs a ton.

It has an explorer v8 emblem stuck to it now, since it just got back from the powdercoater. I blacked out all of the plastic behind it.

 

It is the Ambient Air Temperature Sensor. It provides data for the in cabin outside temperature display. I'm curious as to whether it provides data to the PCM or other on board processor for any other purpose. I ask that question in another thread and didn't get any worthwhile replies. I suspect it serves that singular purpose.

 

Does anyone have a picture of where it is supposed to be mounted to? As of now its just laying on the bottom of the bumper shield above the ground attached to nothing.

Thanks again!

 

it shou;d clip on the vert bar the inside the last left bar
