ScrewThat

Truck is an 02 4.6 supercrew 2wd. I'm throwing these codes. I expect it because I'm running gutted cats. I've done the gotts O2 mod and the drivers side I believe is reading fine. The passenger side is throwing both of these codes. I have my tuner set to turn off the o2's as well and it's still throwing codes. Could it be a faulty sensor? Would it work If I swapped sensors to see if the code followed the sensor? Trying to figure out how to get rid of the codes for when I install my headers in a couple of weeks.
