I have a 2017 Malibu Hybrid w/83,000 miles. I got a CEL w/P015B code, I had (2) o2 sensors replaced and CEL came back on after 2 days. Once cleared, it seems to come back on about every other day. Has anyone else had this issue?

possible that the adaptive memory doesn't recognize the different resistance of the new O2 sensor.

well, not necessarily a flash, although every drive-ability school I go to they tell us to flash the PCM to the current programming before proceeding..
It's just a "reset" of the adaptives to make sure the car doesn't learn bad habits.
