What are the pinouts for a 1jz map sensor?? Is it possible to test the voltage when the map is reading atmospheric to see if it's functioning correctly? I have a GM 3 bar lying around but I can't install it because I don't know what the pinouts are.

 

I tested mine with the car running pull the vac hose off and idle changed quick plug it back in and back to normal idle. Your GM may have different voltages to pressure scale vs. the 1JZ one. Second thought the 1JZ and 2JZ should have the same MAP sensor so find that pinout and you should be good.

 

K thx for the input
