MAF Voltage

MAF Voltage
I am having a smoking problem at startup and when the vehicle is warmed up. I suspect that it may be due to bad MAF wiring. I've already swapped the MAF over to a known good one and it's doing the same thing. I measured the voltage at the MAF pigtails with the ignition in the ON position (engine not on). My readings are below. Can any members confirm with what I got?
I believe the red wire should read 12v. It looks low to me. Is the 11.12v adequate?
Is the .241v for the yellow wire correct for being at "ignition start". I believe it should be 5v, but is the 5v reading when the engine is turned on?
Checked the 20A Engine Sensor fuse and it looks fine.
I also noticed on my cluster that the voltage is reading low. This may be a grounding issue.
