This definitely applies to you. If it stays off I wouldn't worry about it but if it comes back on or you notice it running rough or worse gas mileage then I would worry about it.

It certainly doesn't run rough and I get **** gas mileage either way so it's kinda hard to tell. I feel like I have been getting meh gas mileage as of late, but like I said, that doesn't mean much.

I have deleted those heater resistance codes before. Sometimes they come back and I'll replace the indicated O2 sensor or cats. They don't come back. Cats weren't cheap, but all four on the F150 bit the dust. One bank around 160, the other around 200k

I sure as hell hope that the cats aren't burning out, I only have about 63,500 miles on that thing.
