Do you know if there are multiple GM part numbers for the MAF sensor? Will one denote a "strong" vs a "weak" MAF sensor? From what I've read on this forum only the single letter denotes the type of sensor, "weak", correct? But are there multiple part numbers from GM for the MAF sensor? Thanks |
No, one part number but they have two suppliers making them. The only way to tell them apart is the method above. We keep "strong" sensors around so you can give us a shout if you need one.
