2016 Explorer Multiple code all at once (P0010, p0013, p0020, p0023, p0135, p0141, p0155, p0161, p0443, p0446, p0036)

I have a 2016 Ford Explorer V6 3.5L. Threw a bunch of codes simultaneously (P0010, p0013, p0020, p0023, p0135, p0141, p0155, p0161, p0443, p0446, p0036).

Searching the forums implies maybe a blown fuse (possibly caused by a short in a sensor or wiring causing the fuse to blow).

Like other posts, I cannot find info on which fuse powers the sensors common with the codes above (like O2 heaters, cam shaft, etc).

Anybody know which fuse to look at and/or have a wiring diagram that might show how stuff is fed from the fuse box?


Update:
I did find engine compartment fuse #2 (20amp) "Engine Emissions MIL" blown. Replaced and it didn't immediately blow again (so not a hard permanent short). Cleared the codes... will see if the codes come back and/or if the fuse blows again. If it blows again, then the next task will be to unplug the sensors/actuators one at a time to try and find the short.

Any other ideas?
Thx

You did find the correct fuse (BJB F02) for all of the circuits that were giving you fault codes.

On other Ford vehicles, the most common failure point on this type of circuit that includes O2 sensor heaters is that one of the O2 sensor pigtails has gotten on the exhaust, the insulation has melted, and there is now a short to ground that may come and go based on vibration and movement. This situation is particularly common if there has been recent exhaust, O2 sensor, or transmission work performed as it's too easy to overlook securing a pigtail or harness when finishing up a job.

Let us know what you find.

As you thought, downstream O2 sensor wire was chafed causing an intermittent short. New sensor on order and I’ll be sure to zip tie it clear of obstructions.
