P0102 !?!? I got a ses light and the code was P0102 so i check the fuses and the Sesnsor fuse is blown, i replace the fuse Bam it blows that one too, i try a bigger fuse BAM that one goes as soon as i hit the key. So my Question is what othere sensors run off that fuse ? and where should i start lookin ?!?!
Thanx Brandon

the O2 Heaters and O2 Sensor is powered off this, as well as the MAF ... not sure what else but those are some sensors to check
Since it's blowing them right away (sounds like) then it's a dead short... should be easier to find than a sporatic problem... i'd disconnect the MAF first... replace fuse (don't use bigger than reccommended or damage can occur) ... if it doesn't blow then sounds like a bad MAF
if it's not the MAF then trace the O2 sensor wires up and see if they're hitting hte header (i had a problem where one wire hit hte header and would sporatically blow the fuse while I was driving)
