For those of who need all the information here is something that can help others. The multimeter is out of focus, so I Googled the multimeter model to see it in focus. The multimeter is set to 2K ohms for VS-E2 and VC-E2. It is set to 20K ohms for the temperature tests. Some multimeters drop the k on 2k, so it is written as 2000

just got done with this testing procedure ... it's important to do the last 2 tests (the dynamic tests) because in my case all the static tests listed in the FSM were 100% within spec but when I went beyond the FSM and did the dynamic test, manipulating the vane door, is when I saw where my problems were coming from. The test between E2-VS pins revealed multiple open/short readings in the sweep indicating a worn out resistive strip on the vane door meaning my AFM is toast and in need of replacement or refurbishment.

Thanks for posting this. Helpful.

A question - I bought a new AFM for my 1991 Toyota truck V6. But when I install it, the truck only runs for a few seconds, then dies (It seems like I smell fuel). If I install the old one, it starts immediately and does not die. I am confused; Is it necessary to somehow reset the ACU to the new AFM, or something like that? (I tried disconnecting the battery for a while, but it made no difference). Thanks for any ideas!

You can make a testing subharness by cutting the wire harness end from the wrecking yard and using wire terminals from it.

I got a replacement pigtail for the maf on my 93 4runner can you do a how to on that?

Link is broken. Post another?

link is broken please post it again

Will this work for a 3.0 3VZE 95 4runner

Where can I find the instructions. I need it. For my 1gfe.

the FSM. or www.4crawler.com/4x4/CheapTricks/AFM/index.shtml. 4crawler has so much good info on the 22re.

It's not supposed to go higher than 1000 in the dynamic test. This one tests bad
