Please help! All these codes are showing at once. 2016 Expedition limited
@Dillardsix because you're showing ALL the codes for O2 and Cam sensors, and becsuse it is the ecoboost we're talking about, almost all of these codes can be attributed to intake/emissions controls. With that said, if we look to your codes again, we do see a possible common factor here in the evap codes. It's a closed system and there is no MAF, so a bad sensor/valve here creates rich or lean conditions which will throw codes all the way down stream. In this case that could easily mean the cam and O2 sensors.
If it were me, I'd start with the three common problem sensors on this engine - the Charge Air Intake (CAI) sensor, Camshaft Position Sensor (CPS), and the Positive Crankcase Ventilation (PCV) solenoid. You'll want to inspect each of these for defects in the electrical connections, exposed wiring, improper ground, etc. or in the case of the PCV, a vacuum leak.
I've had similar emissions related codes on my '15 which were all solved by repairing or replacing one of these sensors (after thorough research and diagnostics).
I agree, it is likely an electrical circuit issue, but whether it's wiring or sensor related remains to be determined. I'm just trying to narrow it down for you so you have specific areas to focus on without having to trace ALL your wiring.
Keep us posted on your findings!
