Default Fault Codes and a weird smell while driving

The wife decided to drive the D2 to a jobsite today and it left her stranded there with a no start condition. She got a ride back to the office and I picked her up later on went back to the scene of the crime. It started for me on the first try but it has hella codes now. On the drive back she reported that it had a weird "hot" smell. I could not smell it though.
Current codes are:
P1884
P0102 Mass or Volume Air Flow A Circuit Low
P0445 Evaporative Emission System Purge Control Valve Circuit Shorted
P0448 Evaporative Emission System Vent Control Circuit Shorted
P0340 Camshaft Position Sensor A Circuit Bank 1 or Single Sensor
Pending codes:
P0154, P0134, P0135, P0155, P0141, P0161 - all O2 sensor codes. Believe these to just be a result of the above current codes.
I did replace that purge valve can on the engine with the recommended Hyundai part but that was a year ago or more.
Help!!
Also, my little scanner does a scan that doesn't give P codes and it states these DTC codes:
Mass Air flow sensor fault,
Cannister purge valve fault (power stage),
Purge cannister vent valve/DTML power stage fault,
Camshaft sensor fault\Valve timing error

Yes, I cleared them before she drove it back home and they came back on the 8 mile drive back.

Maybe the weird smell was a wire harness getting melted through? That’s a lot of codes…

Maybe a hose came of your replacement purge valve.

Well based on that I would start with the cam sensor.

Okay, still having the issue.
I replaced the camshaft position sensor with a new one. I also replaced the maf with a new one. I put the old purge valve back in as well. I can clear the codes but all 11 codes come back after cycling the ignition. It doesn't look like i have any burnt wiring but i guess you really cannot tell unless you take all the loom off. I thought maybe the battery being low at 12.02 volts might be an issue but I charged it all night to 13.x volts and still get the codes.
What else do you think it could be?

When did this start? Any work done just before it started. I misread the first post, it is either a bad MAF or a bad maf wiring. Not the cam sensor, those show up due to a bad maf. You can try unplugging the maf completely but since the codes came back with the new one I suspect the wiring now

I found the issue while deep-diving this forum. It was the F2 fuse under the hood. Apparently it supplies power to all those sensors. So now I feel like an idiot for not going on a blown fuse hunt first, Any way, this forum saves the day again!
