Default pink wire on maf,fluctuating 5v or 12v

ok heres my issue;

no maf reading, p0102 code, via hptuners i have flatlined .22 on the maf

i have a good ground, black/white, and the yellow has 5v

is the pink wire supposed to be 12v or fluctuating from 1-5volts. Im getting neither. And also what harness connector(red or blue) does that wire go into.

Im getting in the blue connector a pink wire with no voltage, red i have one pink wire with 12volts. Im trying to see if its a wiring issue, or a PCM issue.

also if its the 12volts, the eng sens fuse is good. What would happened if i ran a jumper 12v wire to it, to see if I received a reading?

Sounds like you have a break or a short in that power Wire..
