Map Sensors!

[Stain]

Okay I have a couple of Map sensors here. But I'm not sure if what I have are 1bar, 2bar or 3bar...

They are both Toyota, but their source are unknown...

89421-12030
89420-32010

first part number: http://www.toyodiy.com/parts/p_J_1984_TOYOTA_COROLLA_AE82-EEMQF_8404.html
second: http://toyota.epc-data.com/vista/sv20/27344/electric/8404/89421/

They are Vacuum sensor so 1bar absolute 0 guage pressure.

At a guess they are blue label for NA motors.

Boost pressure sensors are labelled orange.
GZE, 4EFTE 1JZGTE sensors are all 2bar from my research and I run 1JZ on my 4AGZE no issue (boost cut at 1.2bar)
I also have a 3SGTE sensor which is factory 3bar map, but not so easy to come across.

I also have a 3SGTE sensor which is factory 3bar map, but not so easy to come across.

What model 3SGTE do they come from? Do you have a Part Number?

Thanks anyway,
but not really what I was looking for as they are not really 3 Bar as they wont read up to a full 2 bar above atmosphere.

Good to know though.
I had a play with quite a few years ago trying to find one that would replace a 4AGZE one, but most has different outputs at atmosphere to it.
