Working on a car that had two MAP sensors mounted side by side. One not being used. The one that is hooked up only has the numbers 9756-B6 and PBT-GF30 on it. The other one has a GM number of 12569241 and believe that it is a 2 bar. Trying to find out if the first one listed is a 3 bar but coming up empty. Does not have a GM label on it.
