i have searched several threads on icv and i can not find any ohms measurements for the icv. does anyone have a good one they could test the resistance ? or is there a thread that i should look for? i measured mine and it measured 3.8 ohms. i measured the milliamps and they were around 150 - 220 mA, the pro manual says it should be around 450 mA . i replaced the icu and the same reading. wanted to test the icv for continuity and to ground to make sure it was at least ok from that spec.

If it is humming, then assume it is good.

Mine was humming and it was bad. I was parked out front of Van Cafe and swapped a ton of parts before I learned that a humming ICV can still fail.

this i why i was wanting to check the resistance and check if icv was grounded.

I had an idle issue recently, turned out to be a vacuum leak - but I removed, cleaned and tested my idle valve with a 12V power supply. Car battery would work.

After getting it nice and clean, I figured that if the valve was 'snappy' in its response that it was as functional as it ever was during my ownership.

Ignorance is bliss.

It's amazing the difference a properly working ICV (and all the other components of your Digifant system) can have on your idle.

When it's all working right, it's butter smooth.

the funny thing is that when i disconnect the icv and start the engine it starts a little hard and i have to push the gas pedal but it always starts and runs fine, a little rough until it warms up but then it drives fine and idles fine.
so i dont think i have a vacuum leak or intake air leak or it would show up with the icv disconnected.

Yep! My temporary solution until I got a good ICV was just to leave mine unplugged.

I’m a stickler though and wanted it functioning even though it only lowered the idle a little bit.
