Default AFM out of spec

So I need a new AFM, have for a while now. I checked it with a meter and it's way out of spec, not even close. No code ever came up until it's unplugged. I can grab one from the J/Y but I got a question first. Can I get just the electrical sensor on top or do I need the whole setup? Are they the same 90 - 94?
TIA

Anyone got an answer? I'm going to the JY this weekend for a few items and maybe get the AFM. (Air Flow Meter)
Can I get just the electrical sensor on top or do I need the whole setup? Are they the same 90 - 94? The car at JY is a 90 and mine is 93.

Agree w/ python - same part number for 1990-1994 cars (22250-50010) is for the entire AFM assembly. There is no part listing for just the sensor separate from the body. There is a lot of really fine measurement taking place in there. I would guess that tolerances are pretty important. I’m surprised that AFM’s don’t give more trouble than they seem to. I once had a shop tell me that replacing the air flow meter (to the tune of $800) on my 1990 was part of the 60k mile service. I didn’t see it listed in the owner’s manual so I declined. I'll be interested to hear your conclusion on whether you can swap sensors out of the AFM or must replace the whole assembly.

Thanks guys. Twofanman, I'll let ya know if it works. Now I'm not sure if I'll get to it this weekend b/c of weather. The reason I ask about just the sensor is b/c money is tight and the sensor can be one of those little things from the JY, like electrical connectors or radio *****, that go in your back pocket and "forget" to take out when ya get up to the desk. I gotta get door panel, handle , and a few other things so they'll make thier money off me when I do get there.

That's what I'm wondering, if it will get screwed up.
