When I bought my camaro, the previous owner had put an air cleaner on:




What sensors need to be moved or relocated? I know there are threads and how-to's on doing this but none of them really have pictures.My uncle tells me that I need an air charge sensor. The previous owner put a paperclip into one of the plugs to trick the computer, but I don't know what sensor SHOULD be there. You can see it circled in the picture above.

It's probably the AIr temp sensor you need. you can cut a hole in th ebottom of the air cleaner to mount it there. If you have to pass smog you might needs the thermac, but im not sure where you are. Other than that that's the only sensor they had to mess with to put that air cleaner on.

I was thinking that, the air charge temperature sensor? What is this thing:



Is that the thermac? I'm in MA, and after the car is 15 years old, it doesn't need to pass smog/emissions.

Thats it. Thermac. It diverts air from ext manifold. Base of AC as stated is place to put IAT sensor. IAT sensor is is a 0-5V sensor. I ohm'd mine to see what would happen when it was new. I placed in freezer and as it warmed up sure enough resistance changed. I presume with paper clip in there no resistance. Not sure if that is a good idea. i doubt it is. cheap enough to buy.

SO I need an Intake Air Temperature Sensor and not and Air Charge Temperature Sensor?

RFmaster

You need Inlet Air Temperature (IAT) sensor. OE part # is 25037313 used in 89 (many others) Camaro 305 w/ TBI ("E" engine). There is no 'Air Charge Temperature' sensor on third gen. IAT can be screwed into the base of your open base air cleaner assembly - past inner diamter of the air filter element.

Okay, I ordered one, do I need to make a hole in the air cleaner base, or is there a spot for it already? I never really looked at the base of it. I would right now, but my car isn't here where I live.

u can also relocated somewere in the engine bay, some ppl say its good to put it somewere were theres cooler air but i guess that does nothing, i drilled a hole the size of the sensor on my open element base and left it there, also if i were you i would buy an AC delete pulley and install it in place of the compressor there, the PO sure did a nice job removing the ac lol hey why remove the lines when u can just twist and cut them, i guess he just let all the freon out.

I"m not too sure why he did that haha Is it possible for me to reinstall the parts that he removed so that I can have AC again?

Sure you can. Just replace what is gone.

EDIT: I was looking at the wrong (the 2nd) pic.

That thing, the silver canister looking thing is missing. Not sure what it's called.

They call it the accumulator, or the reciever drier. If your system has been open it's best to flush it out. I would also replace the orifice tube, it'll be easier to flush w/o that in there.

RFmaster

I would look for a spot in the base of the air cleaner plate that is interference free. Most of these open element cleaners were designed for carburetor application - hence no provisions for IAT mount. You'll definitely need to check for interference before drilling a hole for IAT. As side note - these oversize air cleaners feed engine with hot, under-hood air. I would rather feed cold air instead.

What is the orfice tube? Sorry, I don't know ANYTHING about the AC system. Is there a diagram of the system?

I would also prefer cold air, but this is what I have to work with right now.Thanks for the help!

Does anybody have a picture of this sensor installed in their air cleaner?

Check this out. There might be the info you want in there

If that black thing pictured in the link above is the sensor I need, then I ordered the right thing. Thanks guys!

the orifice tube is inline in the a/c hose. your a/c hoses may have been cut or look like they are missing...check out the cooling thread for any a/c questions.

Ronny

I will suggest the proper way to do that is to weld a nut on bottom and thread it in from bottom.

Well, after my uncle told me that I need an air charge temp sensor, and I have seen the same type of sensor being uses on another member's open air cleaner. Is this the right thing?



I can't remember what member is is who has it, or if they are even on this website, I may have gotten it confused. Anyway, is that it?

I am using a 1989 L03 IAT (camaro). It does not look like your photo. The tip is more like a small lipstick protruding for lack of a better word. First one they sold me(1992 L03) was a birdcage looking devise and it would not work.

How exactly can I tell if it works or not?

Ronny

when disconnected it will throw a CE light. connected no CE light.
