St185 and st185 afm (maf) sensor same?

Postby timek1m » Fri Oct 30, 2015 4:58 am

So is the maf sensor for the st185 and 165 the same? Need new maf for st185 and found one for st165. Wondering if it will work. Thanks

The AFM from each car is different. . Will it work, probably but they are not the same. Just like the NA FC3S RX7 AFM, it's the same shape, plug, and manufacturer with only a digit or two difference between the part numbers from the ST185 and I've heard it'll work as well but still, not the same.

If it helps. . I found I had been using the wrong AFM (22250-74180) that was installed by a previous owner and I had daily driven with this from Jan. 2013 up until last week. The incorrect AFM was from a ST162 3SGE.

What you need is part 22250-74200, you could search the junk yards if you have any close to you and find one off any 5th gen Celica no matter the model. . according to this site, they all use the same part. http://www.toyotajaxparts.com/toyota/celica/2225074200/1992-year/st-trim/1-6l-l4-gas-engine/electrical-cat/powertrain-control-scat

Thanks, so much. Found a am and now. That didn't fix anything. I reset everything it idles at 1500 rpm. And then dies after 30 sec. I can't seem to locate any vacation leaks. I'm wondering if it might have to do with my safc.

So I had a blown turbo manifold gasket blew. So I replaced it. And then I started having this idling issue. So I was told it was the maf. And I replaced it. And no fix. There is no vac leak. Any ideas on what it might be?
