2013 Tahoe LS mass air flow sensor

[Just00Jake]

Hello all, I have a 2013 Tahoe LS and I'm getting a P0102 code, mad at for low frequency code. I started troubleshooting the readings on each wire and they were not coming back to what they should have. I'm not reading a ground. I wanted to ask if anyone knew where the MAF ground wire terminated? But at the same time I tried to look up the wire color/lay out to make sure I was dealing with the correct wires as I'm diagnosing. I bought it used of course. My 2005 has the same wires in a different order and everything I've seen online were also different but they were not my model and year so of course I can't use that for comparison so I wondered if anyone had that info? Wire color/order on the actual harness that plugs in to the MAF. THANK YOU VERY MUCH for any help. I appreciate it

Let me revise that post. I get a ground with the key off but not with the key on?
