2018 Silverado 1500 P015A trouble code help

[Christian Olguin]

I know someone on here might know. Been getting this code. It refers to bank 2 which would mean o2 but I’ve replaced that and still get the code every once in a while. I’m running catless longtubes (obviously tuned) any idea anyone?

I see that code a lot with long tubes, the o2 sensor spot isn't ideal compared to the OEM location.

 

I'd just turn the code off.

P015A isn't bank 2.

 

P015A is HO2S Delayed Response Rich to Lean Bank 1 Sensor 1
