Need MAF voltage reading-VIN F or 8
Was hoping someone could probe the dark green wire on their MAF sensor disconnected and tell me the voltage with KOEO? Appreciate any help!

Re: Need MAF voltage reading-VIN F or 8
Thanks, but that is connected. I have to determine what the voltage is disconnected. I have 2.35 connected and 3.72 disconnected. I think I am having 5v reference signal issues. Needing someone else with a good running car to verify though.
