Engine Light Turned Off by Itself??

I had an engine light turn on yesterday reading P015d... Google says its "O2 sensor delayed response – lean to rich bank 2 sensor 1"

Called the dealership to make a service appointment next week. But magically, the light turned off itself this morning

Should I still have it looked at anyways?

I would, they can pull the history on a code even if the light is off now. Besides it will probably come back on in a few key cycles. I would take it in especially if its under warranty

This may mean the sensor for bank 2 is slow to heat up, which can cause a delayed reading during the rich to lean transition
