AFM question

[Tacoma_Kyle]

I read that the AFM I bought is AKA a 'hotwire' AFM. Ok thats fine and dandy, but what kind of AFM is the 90-94? (I thought I had a 96 SC engine, but it was a 95)

So... hotwire AFM's run off a variance in resistance (leading to voltage change), so how do the prior aluminum cased ones work?

I just want to know if this AFM will possibly be usable. If it doesnt work by voltage/res. variances it will clearly not work.

There are a few different MAFs that 1UZ's used, the early generations used Vortech AFMs, by far the crappiest design. Later on they switched the much more reliable hot wire MAFs.

Ok.

Do you know how the vortech ones work? How they measure the airflow...
