5th Gen Camaro no mods
I've had a check engine light on for bank 2 sensor for months I recently had an oil change and now the CEL has turned off. what gives?

forgot to add, v8 motor, 96k miles, manual

I dunno lol. but seriously, OP. a loose gas cap can trigger a CEL. the only way to know exactly is to scan. but it went away so the ECU believes everything is fine.
