    in my 1998 3.4 tacoma, the mass air flow sensor comes welded to a plastic housing, in the 2000 3.4 model, is separate, is screwed the sensor to the housing. it's oviaous there is more airflow in the 2000 unit. Is the same wiring? Can i replace the mass air flow sensor in my 1998 3.4 tacoma (the whole unit) with the one that comes in a 2000 ( the whole unit? 3.4 tacoma? I check all prints for wiring and to me look the same, i think is a plug and play. Any help, is appreciated. Thanx

    K so the 98 is one big god damnit, and the 2000 is the small sensor that screws into the tube right?

    Yeap? But the 2000 is a wider tube. I hear that if i replace the 1998 with a 2000 maff sensor the whole unit will give me a lean code. Is that right? It has the same amount of pins in the connector and in the prints, is the same thing!

    These will answer your pin out questions. I had to swap the pins when I did the TT supra maf conversion. No biggie, a small flat screw driver will release the pin from the connector and just swap the pin positions. I'm going to ditch the supra maf and convert over to the 2000 style in the near future.
