Where is the IAC valve?

robStER · 03-13-2008, 09:26 PM

I have searched on here and used my Chilton manual but I cannot locate the IAC valve on my '93 Sentra SE-R. I just want to remove it and clean it out. I also signed up yesterday to be a paying member so I can download the service manual but apparently it takes a while for that to get set up. Thanks.

Well, I am pretty sure I found the IAC valve but it sure seems difficult to remove. Any advice on removing it? What happened to SE-R.net? It does not seem to be there anymore. Thanks.

nvm i just saw that u said it was a '93 so im not fully sure

SER.net is dead due to a legal dispute.

IACV is near the oil filter. There are 4 10mm bolts attaching it to the IM. It can be tricky to remove if you have AC.

I'm feeling nice, I found this thread for ya:

Greatly appreciated. I had been searching under under 'IAC' and didn't think to look under 'AAC'. I do have the AC and it seams quite difficult to get in there. I actually have a miss at idle and I don't think cleaning this out will fix it but I want to make sure it is clean. I will be checking my injectors soon and then for vacuum leaks. Thanks very much again.

Sounds like you've got a pretty good idea of how to approach the problem. Hope you fix it.

Is it located in the same place on lowports too?

Very close, but even easier to get to.

SR20WhoKnew · 03-17-2008, 12:41 AM

could someone point out where exactly it is on a lowport or even a picture?
And what can I use to clean it?
Thanks

It's the exact same part, in the same place. It's just about 6" higher (about where his hand is).

Well, I finally got around to removing the AAC valve and pretty hard to do with all the power steering/AC stuff in the way. Anyway, while I was wrestling it out of that confined space it appeared that a small spring fell to the ground at that time. So I am assuming it fell out of the AAC valve. I included a pic with the small spring circled. I cannot figure out where this goes inside the AAC valve. Any input?
