I also had the same exact experience. Replaced everything: plugs, coils, CCV hoses, pre and post O2 sensors. Still had the fault. As terrible as it sounds mine eventually went away after about 500miles after replacing the O2 sensors.

Good information, thank you so much! I have pretty damn strong hands, but they are also gorilla sized, so when I looked into that space where the hose is routed to, I said no way, lol. It looks like it would be easier to from underneath the car?
Right now my car has 108k and this time I just did the two upper hoses. At 73k I had my mechanic replace all four hoses, but when i was doing spark plugs and coils I noticed some oil seepage on the upper hoses, so I replaced them. They are made out of such brittle plastic, my washing machine discharge pipe if 10x more durable. The dealer had replaced all four of them back in 2015 with just 17k miles on the car when they were doing the injectors recall, and then they replaced just one of the upper hoses at 59k when they were doing the valve seals recall.
I guess I'll order the two lower hoses and try to tackle them, if that doesn't work I'll just have my mechanic do it. And might as well get two new precat O2 sensors. Did you go with genuine sensors, or Bosch OE sensors?
Also, did the error go away after 500 miles by itself, or did you have to keep erasing it until it stopped triggering? Did you reset fuel trim adaptations?
