no it needs to be in front of the radiator support,so it can get fresh outside air.if you put it in the engine compartment,your outside temperature gauge will be reading the underhood temp.

 

I duck taped the remote unit to my wireless thermometer just to the side of the radiiator. It is a pretty acurate location, enven being held on with duck tape and not really designed for a vehicle.

 

yea thats what i did, i'll take pics later of where i put it. now.. its time for work :/

If I recall correctly, both the engine control computer and the HVAC computer use the input from that sensor. I'd want it to be in an environment as close to the factory original location as possible.

 

IT doesnt do both, just the overhead console temp.

 

The sensor is present in trucks that don't have the overhead temp/compass console. I am certain that it is used by the HVAC controller in '09+ vehicles. I think it is also used by the engine control computer. I'll look for documentation on both.

 

i dont have one, as well as two of my buddies. MAybe it's just an 09+ thing?

 

This is interesting. Thanks Lrgrnr. Anyone every have inaccurate readings for outside air temps? Mine seems always off compared to other vehicles, , my digital house thermometer, weather report, and my Bacharach field thermometer. My Taco (2006) temp is 5-8 degrees warmer when it is colder outside.
