hey everyone,
I have a 3.0 90 pickup and the maf sensor is not doing its job. I actually went to a pick n' pull to see if i could find the part and i did, but the thing is, is that it was on a 4 cyl pickup...the sensor looks exactly the same as the one on my truck, i mean exactly. The only problem is, is that there is a there is a serial code on it. its split with 2 5 digit numbers for example: XXXXX XXXXX.
the first five digits are the same and i believe its 25000(not sure im at work) but the last 5 are different. I know my friend who has a 4runner(same engine) has the same serial code as my truck. So the question is do could i use that part i found even though the number is different or should i go with the same exact part with the same (part)number as the one on my truck right now. here is the what both sensors look like.

thanks.

 

I doubt they are the same, but don't know for sure. Even if it was the same box they may be calibrated differently. BTW its not a MAF (mass air flow sensor) its a AFM (air flow meter). Two different types of air flow measurement systems.

 

Try it and see if it works. Some times they do and sometimes they don't.

 

MT Goat:
What is the difference between the maf and afm?

 

pretty sure they arent the same but i could be wrong....
and afm=air flow meter( what the 3.0 has)
maf=mass air flow sensor or something like that

the 3.0 has a AFM not MAF

also, theres a good thread about what afm's work and which dont, search for it its very helpful.
you can also use a camry afm or a couple others i cant think of off the top of my head.
i used a 91 or 90 camry afm, you just have to fab a little, not much though.
very noticeable size difference(in the metal intake hole part) and power difference from the camry afm

 

You noticed a power difference when you installed the alternate AFM??? A good difference or a bad difference??

 

Sorry i should have clarified- yes, a very good difference. Way more throttle response and better power/accel. I did the afm swap and the isr mod at the same time and im very pleased, the 3.0 isnt as slow anymore. It also sounds great when i step on it

 

its an AFM id did a supra swap on my 22re and it helped alot

 

The 4cyl and V6 are different. The 4cyl's wiring is different and has a smaller opening.
