I just installed a GM 3 bar MAP sensor on my 1jz setup but was not sure what voltage it is supposed to be reading on the ignition on position. When using the stock MAP sensor I'd get the reading of 2.xx volts, but on the GM 3 bar MAP sensor I would get 0.7 volts. I was wondering if any one can relate some feedback on there 3 bar map sensor voltage on the ignition on position. Thank you!
Question on GM 3 bar Map sensor
- Thread starter retromania
- Start date
I just need to know the MAP sensor if it is in proper working order. Are you by any chance using a 3 bar map sensor?
I assume your talking key on, engine off? So around 100 kpa , readings should be around 1.5 -1.7v. But that reading will go down as you go higher in altitude. A reading of .7 would be normal at 6000-7000 feet above seal level.
I found that here.

yes ignition on engine off, thank you for the response by the way.
I already saw those links before, but I wanted to know first hand from fellow members using the 3 bar map sensor what their voltages were on their cars.
