Default MAF voltage test

Your MAF plug is located on the throttle body. Lift tab(underneath) and wiggle while pulling the plug, not the wires.

Now take your multimeter and put the red probe on the pink wire and the black probe on the center black wire, with the key at the run position, with engine off

You should get battery voltage.
