Fire up w/ new cam & MSD Timing twister P0343 code? Hey guys,
I installed a new big cam, springs etc along with a good working MSD timing twister to run inline with my N2O setup etc. on my 2001 LQ4/4l80e combo and long story short while running it was getting a PO343 "Cam position sensor voltage high" and it never had this before the cam swap, so i unplugged the MSD TT and ran it again and the code never came back.
So needless to say i'm really confused how this can be? The MSD only has a red, black, and blue wire to hook up, red + while cranking so I hooked it to the PCM + so it is powered when PCM is on, black obviously a ground, and blue is the actvation wire thats not on unless the N2O is on.
Any help????

FYI, I called MSD and the guy wasn't much help....... he said that i've got my cam sensor wires switch around, wouldn't that be impossible since the code doesn't show up until I plug the MSD TT in?
He made no sense
