check the wires to the plug for the maf for cracks or bare wire showing.

also check your fuse box, that the low voltage code, its fuse may have blown. same for the wires, bad wires will make the low voltage code pop up.

maf maybe just fine.
 


Its number 21 in Underwood box. Im battling this right now too. I changed by o2 sensor cuz it was throwing every code you could get for the upstream o2 lol and after change it would blow that fuse. Thought it was just a bad o2 so tired another and same thing. Did find out though that both o2s (I think) and the evap solenoid and maf are all wired to that same circuit so ive got some wires to trace down and find the short
