*EDIT*
( These all turned out to be old stored codes on the cars computer. Refer to my response below for a more detailed explanation)

Anybody have an idea what could be the culprit for some of these? I believe I’m probably going to end up taking it to a shop. But any insight would be greatly appreciated. Maybe I can sort this out.


I have an idea what is causing the p0462/fuel level sensor code. I'm thinking most of the other codes are all being caused by couple things, just not 100% what could be up.

 

Well, for the Body Control Module codes, It may be possible that your BCM has gotten wet. Unfortunately, we have a common issue in these cars wherein the sunroof drain tubes clog at the end, and the water backs up and floods the BCM area. On my car, I had puddles on the passenger AND driver side floors. I was able to unclog and flush out the drains with some drano, hot water and some shots of air from my air compressor.

Check the passenger side floorboard area for moisture and take it from there. You can remove the trim pieces to the right to inspect the condition of your BCM. If there is evidence that it has gotten wet, then that may very well be a major chunk of your issue right there.

 

I agree.

You have almost all of the Fuel Level sensor codes

You then have quite a bit of ABS codes where it doesnt register wheel speed sensors or the ABS unit communicating with the CAN BUS

More insight on how and when did these codes developed would be great. For all we know you went sideways, hit something and shorted out the ABS fuse as well as broke your sending unit throwing all of those codes. This could also be a wet ECM and or damaged ABS unit.

 

I did think that was a possibility too, that the BCM had failed. But thankfully that is not the case. I started with the battery which was fine, makes sense lol.

So pretty much, those all turned out to just be old stored codes. Or at least I’m almost positive at this point. This is a newly purchased car. When I bought it we used a typical obd2 scanner to pull all the codes. I got the p0462/fuel level sensor codes, which I know is a common issue on these cars.
Anyways, fast forward a few days after purchasing the car I used my blue driver Bluetooth code reader to do a full diagnostic report of codes. That is when I pulled up the 19 codes. I spoke to the previous owner after confronting them, and many of these codes they’d had before and had fixed the issues. Including a bad battery, a bad speed sensor, etc.
Using the obd2 scanner at Oriellys only the p0462 code came up well, I checked just to be sure. Guess the blue driver is just a super good tool.

I’ve cleared the codes, and after over 100 miles only the p0462 has come back as it should.
