here is a link to my thread but i realized it was in the wrong forum most likely.

You say you thoroughly reseached this, but think P0102 is an O2 sensor related problem?

 

no it is maf sensor low voltage. however it appears that it is run on the same circuit as the 02 sensor power wires so them melting and grounding out could cause the eng sens fuse to blow and therefore not give any power to the MAF. i know that it is not an 02 problem directly however it in many cases, not all, related.

why dont you check resistance at the maf? see if you didnt fry the maf or check to see if any of them circuits are grounded to the PCM
