3 bar MAPs ????

[grocerygetter]

I've got like 6 GM MAP sensors. 2 or 3 are supposed to be 3 bars...maybe more are 3 bars...how can I tell which is which. These came from a friend that used to have a perfomance shop and had these laying around from import turbo kits. I'll sell what we don't keep if anyone needs a 3 bar map.

They all will have part numbers on them. You can post the numbers.. maybe its a common #. Or call a GM dealer with the number see if he can decode what it is.

Sure fire way of knowing, is apply 5 volts to the pin labeled "C" and ground to the pin "A". Measure voltage at pin "B". If it reads 1.6volts DC its a 3 bar.

Careful selling sensors that may not be... someone can hurt a motor if the cal is different.
