Hello I have and 09 ford explorer with multiple fault codes for o2 heater circuits, egr, and purge valve. Paul just put a video on youtube that's basically the exact car and fault. I've made a call on the pcm but it's 2 weeks out and I'm hoping somebody could maybe ask Paul if the pcm is what he found or if I missed something. I don't really want to wait to the releases the next video to see if there is something I missed. I to choose to test the purge valve all the way to the pcm and found no issue. I can run bidirectional controls an each circuit without an issue. I just thought there had to be a fault internal to the pcm on the monitor circuit. The picture is scope hooked up at pcm on the control wire of the purge. I also checked pcm grounds but found no issue.
