Re: Hunting down a P0174 problem
The position for the damage was on the head bolt sticking up just to the left of injector 6 connector on your diagram. It runs over the transmission and hugs that corner of the cylinderhead.
ultimately when I found the one I had, the harness was too tight to get it out, I would have had to dissassembly much of the harness and spliced in a new long section... Considering the severity of the situation, the insulation had litterally JUST been nicked through, I cleaned the area, installed some liquid electrical tape to seal the wire up and then used some harness tape (like a cloth electrical tape) to wrap up the conviluted tubing very well, I then did what I could to position the harness away from the bolt. Worked like a champ!
