Hi Folks,
I have an odd issue, I have several codes (see picture) all related to power for the EGR, all 4 oxs sensor heater circuit and the PCV valve, they're all on the same circuit, fuse #42 (fuse is good).
I've cleared the codes several times, I also replaced the EGR valve and all 4 oxs sensors, I then discovered it's a power issue.
After all the troubleshooting, I believe it's a bad connection in the harness, I think it got wet from pressure washing the engine.
What I'm trying to find...
'08 Explorer no power for o2 heater circut
