I did back probe it first and had voltage. I didn’t want to cut the wire to isolate, that’s when I pulled the plug and tested directly to the pcm pin. Still had 4.5 volts. Vref voltage isn’t low, I’ve just got 4.5 volts on that return pin, which should have 0 volts with that connector unplugged. I really don’t see how that could be a false trail when I’m going right to the pcm and bypassing everything that the harness could be shorted to. But I’m all ears for all ideas/suggestions you’ve got.
