P0141 secondary O2 sensor

[Alloy]

Light had come on after some normal driving and idling. I have a catted MAP DP with catback exhaust, JLT intake (just cleaned a week ago), etc...I have a tune from Adam that's a work in progress but that's been on there for 2 months. The catback V band clamps just aft of the DP were damaged due to a steep curb when exiting a parking lot about 1 month ago. No signs of exhaust leakage. O2 sensor wiring is perfect. Not melted, not kinked and no signs of wear. The sensor is secured in place. The only recent thing I did was clean and oil the air filter with the proper amount of oil that I let sit before installing on car. I cleared the code yesterday and drove it briefly with no CEL coming back on. I still need to check the inside of the intake tube to verify no oil from the filter is in there. Other than that, I'm out of ideas. Thoughts? suggestions? Tips?

I have the exact same thing going on, just started yesterday. I'm also getting a P0054 code at the same time as the P0141. I have a catless MAP DP though, with Adam's tune. He says he has a fix, I will let you know what it is!

EDIT: Just saw the date. You've probably already fixed it.
