Our cars use A Hot wire type MAF. not Hot film type
So 0v on the Hot film data "may be" what you want to see.
Just depends on how the Duramatic software is set up
I have always disregarded the hot film data and just looked at the other MAF data.
If your getting air temp. data and Mass Air flow data then both parts of the MAF are working.

Got everything buttoned up and she drives great!!!! New pedal is so much smoother and feels like it has much more travel. Feels great. I checked everything after filling up and driving around for a bit and the ecu is adapting and adjusting fuel trims properly. Everything looks normal and functioning well.
One note about the wire, I initially tried grounding the wire to one of the ground points on the front of the engine block, however, I noticed it wouldn’t run smooth on that ground, and there were stored codes still. I changed the ground point to the chassis. There’s a bolt hole in the body right near the MAF so I grounded it there using a bolt. Reset everything and calibrated throttle and it started up and ran flawlessly.
I don’t know if I’ll end up with this car, I sure love it to death. Considering it’s got 140k miles I might just leave the bandaid fix until it blows, or maybe it’ll go for another 50k miles who knows. Either way, I’m glad I could sort the issue in time, and can drop it off and enjoy my trip. A lot of blood sweat and money in this thing.
