time for a round of guess that map. I got a good deal on what i am told to be a 3bar map sensor but is does not have any usual marking.

It looks like a GM/ Motec map, the only numbers on it are 1008B14 in yellow letters on the side of it. It looks identical to this but so do 15 others on the market. if anyone can identify this model/ serial number i would be grateful
the one picture it similar only with different numbers as stated:

 

Looks like a common gm 3 bar to me...

.. As for myself, I don't see the need for all this mess when you can get a plug n play omni/ hondata 4 bar for $99 or less

 

yup you would be correct...3bar map

omni map

 

but how can i tell if its not a 2 or a 1 bar map? using thisguide there are multiple ranges of sensor mounted in the same box but i dont know which on i have so can i test it with resistance. resistance from A to C is 1673ohm and from A to B 60.4 Kohm

If i apply 5v to A and C i get 0 from B so whats up?

 

you can tell by the model number on it. that is a 3bar

 

Wire it up and hook a vacuum/pressure tester to the nipple on it. See where it stops reading pressure :/

 

yes i could do that but i dont have a vac/pres tester. I was hoping some one could tell me how they work more specifically than the piezoelectric effect. i want to know if my resistances are correct

 

1 bar and baro sensor has different key way. 2 and 3 bar have the same key way. and the pin out is a- ov b- sig c- 5v
