I have 2 MAP sensors that I have NO idea of their ability to measure pressure. 1 Bar, 2 Bar, or 3 Bar?

GM Part Numbers:
12569241
12569240

They have no distinguishing marks on them, only the part number, Lot number and another number above.

16040749 is the p/n on my 3 bar
16254539 is the p/n on my 2 bar
(both are GM MAP sensors)
