1991 MAF Interchange (1 Viewer)

[USOffRoad]

I've searched but can't find this here. Isn't there an interchange for the 91-92 Mass Air Flow sensor? Maybe from a Camry? Can anyone verify? PN's?

Found this on the 80 Series USA FB group.

93 Camry V6 or 92-93 ES300

91/92 had an AFM. Any 3FE equipped Land Cruiser is compatible . FJ62 or FJ80.

I know any 3FE is compatible but just go find a new one... not any.

Their is a kit available I believe to convert the 3fe afm to a maf sensor. Its about 800 bucks. Split second sells it.

Go read that thread I posted above.

I have a used one if you want to go that route

 

[USOffRoad]

I appreciate it... and I might but have already ordered a reman Camry version as shown above. We shall see.....

• The mass air flow sensor for (93?) Camry fits the 1992 FJ80 3FE. I used it on mine in a mid-life motor baseline / refresh, and it runs much stronger than it previously did.

Good info there. @Yackster was in a pinch and swapped the one off his 80 to his 62. Direct swap also.

Good info.

By the way I always thought these were called a VAF, not MAF. (vane airflow meter).

 

[SUMMIT CRUISERS]

Just for clarification, 91 to 92's use the AFM (Air Flow Meter) that uses a mechanical barn door that opens to measure the air flow. Whatever you drive, if it has a mechanical door then they are called an AFM.
If it has a single sensor wire, then MAF sensor.

Before with afm (air flow meter):

After converted to maf (mass airflow meter) this is a kit you can buy so u don't have to use a afm anymore.

So, for clarity, and for those who may go shopping, the device that the OP was asking about, and that is pictured in my post above, is commonly called an "air flow meter," but is sold and marketed as a "mass air flow sensor" - correct?

 

[Technician1985]

Unless you have a mazda then they call it a VAF! It is not a "mass air flow sensor" because it does not measure the mass flow rate of the air directly. the "flap" is AKA a "vane" (I guess if you have a mazda anyway) otherwise it is an "air flow meter" which is accurate yet less specific.

The AFM from the 3vzfe (Camry) and the 7mge (Supra and Cressida) are the ones you want. Toyota made two different sizes of these AFMs. The smalller ones come in the 3vze and 22re engines (4runners and T100s) The Camry and the Supras had the larger one. GO figure. Electrically they are all pretty much the same. same connectors and pin out.

You'll notice a bit of a power increase when you put either the Camry or the Supras AFM on the 3FE. The 3FEs AFR runs richer than stoich. Changing the AFM leans it out a little due to the AFR set for a different (smaller engine).

If you pop the black cover plate off you can see the spring and cog wheel. mark where the cog is so you can go back to factory setting. adjust it in either direction to add or subtract fuel.

Aftermarket sources (Amazon, Rock Auto, etc) for the replacement Toyota AFM can name it what ever they choose to. For the correct Toyota nomenclature, the one with the barn door is referred to an AFM. Very simple to recognize also, the Toyota AFM is constructed of a 1/4 circle for the placement and movement of the swinging barn door.

I hope it adds power because I desperately need more with the 35's! I got one from amazon warehouse deals for $32 shipped because of "damaged packaging". Should be here Tuesday.
