dont know if you are getting it.

Test number 3: the 2nd wire BECOMES a ground when the system is turned on; that is, when you turn on the ac or the headlights. with those off, then there should not be voltage.

Test number 4: the leads of the voltmeter are on the positive wire (black/yellow - that is a black wire with a yellow stripe) and the gound (negative) of your battery. And the key is also ON for this test as it is for number 3.

the price at autozone should be about 190 (but i will check for you).

if you did not set the ohmmeter to the right settings in doing test number 1 - you may have a faulty reading. but if it is zero, then there is an internal short in the iacv.

 

i am not for sure if your setup is the same (SIGH).
is this throttle body or port fuel injection.
and coupe, sedan, or hatchback ??

did not see it listed in autozone.

 

found it - guess it is the same thing; and troubleshoot the same - not sure though.
hope this links: (183.99 - there are 2 different ones)

OK I was confused but now I understand I check for continuity on the ground wire of the 2 and it is grounded all the time, when the key is on with no a/c or lights the yellow and black wire has 12volts when I turn the a/c on the y-b wire has no power at all and the other wire is always grounded, I checked for resistance on another iacv I have off a good running car that i bought the iacv to try on my car and the resistance is .013 so not much difference but it is not the exact same style of iacv but it will bolt on and plug in so i would think it would work. Im not sure what this means but if you have any ideas let me know I thank you for all of your help so far.

 

i dont know the specs for 92 since my manual only goes to 91.
best to put the other one on and see if it idles OK.

 

I have all ready tryed both of them and no good they are the same whitch makes me think its not he iacv but I dont know
