Anyone know of a way to test iac in junkyard to see if good? I know i can check ohms but would not be able to get power to it to see if solenoid is good at 25 bucks i would like to make sure it works. Would luv a new mopar one but 150 is a lot of cabbage

 

You can get a brand new one for $35.00, why are you buying a junk yard one for $25.00? And the Mopar one is only $93.00 at www.rockauto.com.

 

Ah yes rock auto. Forgot. Well i have learned if it plugs into the engine, i better get mopar. Otherwise my jeeps spits it out in a week

 

I know this doesn't answer your question, but I got an oem one off ebay delivered to my door in 3 days from a dealership in Az for 70$.

 

My understanding is you can damage the IAC by applying power to it. Just do the ohms test. Mine tested bad so against my better judgement and advice from others not to I bought an aftermarket one from Rock Auto. Around $30 and so far so good.

 

If you get a multi meter you can test your IAC.


IAC ohms test:
Pin sequence;
A B C D
A to D/B to C = 40 to 80 ohms
A to B/C to D = open

 

Yeah i did test it. Mine was getting 12 volts and the ohms checked out but the pintle thingy never moved and you could feel the solenoid trying to move it
