Can someone with a 2004.5 2005 lly duramax go to there maf sensor connector and test DC voltage on the connector pins? I could have swore there should be TWO 5volt singal pins. One for the IAT sensor and one for the MAF sensor.
There should be 2 5volt, 2 ground, and 1 12volt.
The shop is telling me there is only one 5volt signal wire. It's got me wondering if one 5v signal wire is incoming and the other one is outgoing.
Thanks guys!
