I have two GM Map Sensors but I cant tell if they are 1, 2 or 3 bar. They have some numbers stamped into them but none match up to the part numbers I have for GM Maps. Maybe one of you will recognize these numbers.

Map 1: 886 3168
Map 2: 039 5128

 

yo man, i have a GM 3Bar map sensor and the numbers on the back say 749 7316, so i guess you have a 1 and 2, im guessing, i would get a second opinion, but i figured id go downstairs and look for ya, good luck, RON

 

I suspect one is a 1 bar and one is a 2, thanks a lot for looking. I want install the 2 bar if I can just work out which one it is.

 

mine says 749 7218 and it is a 3 bar map sensor

 

It seems like the first three digits of the number stamped on the back designates how many bar it supports.

1bar: 039
2bar: 886
3bar: 749

 

no prob man, good luck

 

If you still need help finding a GM 3 bar map sensor, go to any autoparts store that carries AC Delco parts and ask for part number 213-101.
