I am 99% sure but it is that last 1% that bothers me. Does the air temp sensor on a FD3s need to be grounded?. I am moving mine to where my BOV was in my Greddy elbow and insulating it with a type of plastic so it won't be affected by heat transfer. If you are not sure, please don't respond. 2 people have already given me opposite answers.

Thanks - in advance for any input.

I'd also like to know. I want to relocate mine.

it shouldnt cause its just a fancy resistor, but it wouldnt be hard to check

True but the car is apart and I was planning on machining and welding the fittings Saturday. I don't know how to check it other than plugging it through the computer. I am not an electrical wiz so basic wiring problems are complicated for me. I can cut / weld / fabricate but ( Thinking is out of the question. My mother said she dropped me several times.) If you could explain how to check it I will - Thanks -

No, it does not need to be grounded. That is why it has two wires.

The thermal swicth has to be grounded as it is a one wire.

The PFC forum had a big discussion on it.

Thanks. I should of done a search. See - like I said. My MOM dropped me several times. I'll chech the PFC Forum

Mine is now mounted in the IC outlet tube which has silicone hoses on both ends. It works fine (reasonable readings on the PFC).

Last week I tested the resistance and did a few other checks and was 99% sure that it didn't need to be grounded. It is nice to hear someone has isolated the sending unit and it stile works. I will be able to hook it up to my wiring harness soon.
I just finished fabricating my fittings / welding and did a few other mods but I can't finish because I miss-placed my porting kit with all my cutters, sanding disks and custom extension pieces that I have made for various jobs over the years. This means that I can't clean up the interior of my pipes until I figure out who borrowed it or where I put it last. Just Frigin typical. I just love being so organized. I guess it is time to suck down a cold one.
