Confirmed air regulator replacement

Postby sjbsuperman1425 » Wed Jul 18, 2012 1:58 pm

Autozone part #AC422 for a 92 sentra. Had the same connector as the factory CA18.

Side by side!

Haven't got a cold start to test it with yet. Will have to wait until tomorrow when I go to work but everything fits and was a straight drop in replacement. Tested it and read 70ohms while the old one I could barely get a reading on and when I did it was around 140ohms.

Awesome info. So I'm assuming it's specifically for the Sentra SE-R right (with the SR20DE)? Not the basemodel 1.6 engine.

Either way, part number AC422.

Was there ever a confirmed Idle Control (AAC) replacement crossover for us?

It's got to be for the SE-R.

Hey sorry I can see this is an old post but I have a question. To replace this part can it be done without taking the radiator hose off? It looks crowded there. What do you think is the best way to go about the replacement?

It's been a while, but IIRC, you can do it with out taking off the upper radiator hose, but it makes it a real big PITA.
