I did a search on OAT sensor and only came up with a thread on harness's.
My question is this.
I am putting an intercooler on the turbo this week and when I pulled the plastic cover off the grill support I saw the OAT sensor. Always wondered where it was.
Does the sensor affect anything else on the truck like cold weather starts or something?
If it does not and only reports to the DIC, what is it's range?
Can it be used in the intercooler air discharge side to read the air temps?

Unplug and see if snything weird happens.

Sounds doable.

Im in for results. Seems like a good idea.

I think you should try it! Its a great idea, however , I don't think it will work very well because the gauge is buffered and will not react as fast as I would like. Its still worth a try! If it works, I will do it to my truck. Hell, I might try it out anyways! Thanks

If you're referring to the sensor on the passenger side behind the grill I had mine unplugged for a week without noticing anything different.

X2. I've been running with mine out of my truck. I'd like to put it back it, but the intercooler was my main priority at the time. Because race truck. Temperature gauge in the mirror doesnt work obviously.

In for results!

I installed the intercooler yesterday.
I took the OAT sensor and trimmed the sides off. They appear to have no use in the application for my truck but it looks like it can snap into something for a different connection.
The sides had to go.
Then, before I put the connection together, I drilled a hole through the silicone connector and the end of the 90 it was on. This will make sure nothing can move. Also, if I just put the sensor between the pipe ends in the connector, when I put the hose clamp on the secure it, it would just push the connector out of round. This way, the sensor actually seals against a solid surface.

I did a short run yesterday and the discharge side of the turbo was 123 degrees and the sensor read 82. Shooting the outside of the pipe in the engine bay with a temp gun I got 87 degrees.

Why not just use the IAT sensor? That's what it is there for.... mine was about 12 inches before the tb, after the BOV. Isn't this what you are seeking?

My MAF is set as draw through so it's before the turbo.

Now I know what's going into the turbo and what's coming out of the intercooler.
This is after about 45 miles of easy driving this morning.
Normally I'm finding it to run 10 degrees higher out of the intercooler than the OAT.

Go to the dealership and buy an IAT sensor for a 1998 camaro with an LS1. Then find the two wires out of five for the maf that are for the built in IAT sensor, and run them to your new camaro sensor. Then drill a hole in your intake tube just before the throttle body, and insert your camaro sensor. Now you can read actual IAT's going into the intake and the truck will pull the correct timing related to the intake air temps. Knowing the intake temps before the intercooler is worthless unless your trying to calculate intercooler efficiency.
