In troubleshooting my PCM intermittent issue, I went to the JY and got a PCM and harness... I was just going to swap both out. I was trimming the garness and realized there was no B16 and it's not on my current harness either. The donir vehicle had to have EGR... so what is the deal?
Also F15 (pink) was not populated in the harness either.
Does anyone have any input as to why the discrepancy?
B16 is egr pintle position, used only on some vehicles but not all I think. My knowledge of EGR is very limited. EGR control is E1. I think it has to do with with different types of egr used on different engines/vehicles, and possiably might have something to do with CA emissions.
F15 is ignition feed, but so is E15. Not sure why they have two pins for the same thing. Maybe someone else can chime in on that one. I think I only have 1 hooked up on mine.
