Customer Question

Hello Mark, I found this topic and possibly you can help me out, I have a 2002 duramax and im getting a P0101 code. I have pretty much followed the instructions you left a couple of years ago, and everything seems to be alright. I am down to ringing out wiring between the computer and MAF, but it would be easier to do in i had pin out numbers and wire colors. any help would be welcomed.

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The expert you have requested is not on line so I will try and help you. Since you have already replaced the MAF three time I would agree and you may be dealing with a wiring concern. I have enclosed the diagnostic steps as well as the wiring diagram for the MAF circuit, hopefully this will help you get this resolved. Copy and past the links to your browser to open and view them.
