Has anyone run into P0102 MAF low frequency? I'm trying to fix my 2002 F-body. The MAF is not working as I have this code present. The MAF itself is good as I've tried another new MAF and still the code appears. Does anyone have a diagnostic manual to guide me or other words of advice? I'm waiting on mine to arrive.

My MAf wasnt reading as well last time i was tuning it on hp tuners. Check the fuses. turned out to be a fuse. I never knew that could be a problem with the maf but it was.

I had a blown fuse at one time but it is good now. The car is a heads and cam car. I think it is a wiring issue but I don't have a wiring diagram to trace. Of the three wires going to the MAF the signal circuit and ground appear to be fine. But the ignition feed is not but I'm not sure how to check.

Other than the CEL being on does the car drive fine? In other words does it have any driveability issues, i.e rough idle, hesitation, running rich (black smoke from the tailpipe)?

Question is do you have any frequency read at the PCM?
This is your fork in the road.
No frequency, look at power, wiring.
Sensible frequency like 2-3kHz at idle, figure it is the PCM
whining because you modded up and it didn't get any.
