I used to get these codes pop up on rare occasions during WOT. I would just clear it and not see it again for along time. I can't remember last time it happened. Really didn't bother me. Jump forward to yesterday. I installed PPE catted downpipes and get these codes now on every WOT pull. I'm thinking bad sensors. Strange that downpipes would make this problem come to light. Haven't noticed a performance problem. Actually runs better with the new DP install. Any ideas of what to do? My gut feeling is to replace both primary sensors bank one and two.
