thanks bdub215. that is the map sensor. you should have one located in the same spot. mine is relocated to my intake manifold since i am using a 7th gen celica throttle body and intake manifold. the celicas are all maf so there is no spot for the map sensor on its throttle body.

the sensor in the air box is the AIT or air intake temp sensor. it should fit snuggly in the pipe. 89-99 are the same mechanically and electronically. so a 98 version would be the same.

no its for the map engine. you need to transfer a grommet into that hole to seal the sensor up. that is why the hole is larger.

^^^ If you are a 1998 or 1999 Corolla - you don't have a MAF, you have a MAP sensor. (NOTE: Look at the second post, already answered here).

If you are a 2000+, then using any quick drying, non-chlorinated solvent will work. They do make specific MAF spray solvents, a decent one that is can be found most anyplace is made by CRC. The MAFs on the Corollas are the hot-wire type, so no danger to damage them unless you physically touch the sensor wire.

no.

the map sensor or manifold absolute pressure sensor does not have air moving through it like a maf or mass air flow sensor would. the map instead reads barometric and atomspheric pressure changes inside the intake manifold. usually it will take a base barometric reading before the first start of the car, then switches over to reading absolute pressure.

a mass air flow meter uses a "hot wire" thermo-probe heated to a designated temperature . the air flowing over this probe causes the temp to drop. the ecu interprets this as more incoming air and increases voltage to the probe to maintain the designated temp. this is how it knows more air is entering the engine and corrects for proper fueling.


also the only toyota/lexus vehicles to use the karman vortex sensor were all powered by the 1uzfe 4.0l v8. iirc sc400, ls400, gs400.
