So I tested my Vaf meter today according to manual spec and readings are as follows.
E2-VS - closed 295 ohms and open is 167 ohms also reading jumps up and down (examp. 295-411-344-256-522-264-364-167) is this normal?
E2-Vc - closed 280 ohms and doesn't change from closed to open
E2-THA- closed- 2270 ohms and also doesn't change from closed to open
According to these readings would you say I have a bad VAF?

Re: Need help with VAF testing
If your using an digital meter then ya your readings will be all over the place at times. I'd start by cleaning the resistance wire, you have to be delicate so don't blast the throttle body/maf cleaner at it.

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Re: Need help with VAF testing
Is it normal for readings not to move on two of the tests when opening? Thanks for the reply.

Re: Need help with VAF testing
How do I clean resistance wire and why would my readings be all over the place if using a digital multimeter? Thanks
Re: Need help with VAF testing
Just check out Youtube, there's videos there showing how to clean the resistance wire(s) in your vaf. Digital gauges bounce around a lot where as analog gauges tend to give a more stable reading.

Re: Need help with VAF testing
I understand digital meters bounce around, but when I hold it in one position and is showing an incorrect reading then I feel its probably accurate. I've tested them before just been awhile but don't remember second guessing my results. I also didn't find any videos on cleaning VAF's just MAF's.

Re: Need help with VAF testing
Figured it out on my own as I usually do. Thanks Dan for trying.
Funny how when I notice just the littlest decrease in performance, I instantly start diagnosing and testing everything and sure enough even though I had no codes there was still a problem. Damn I love a properly running N/A ZE!
