So this code popped up on me last weekend before I parked it Monday night because of my hub bearing. I believe it was the same code Saturday night when I was filling up. I left it running while filling. I thought maybe it was for the gas cap off. Light went out on Sunday but came back on monday. There isn’t any issue I have noticed physically. I cleared it this afternoon with my bro in-laws scanner. After driving it around tonight for at least 1 1/2 hours combined time, it has not come back. What should I be looking for. I’ll be checking to see if the throttle blade looks dirty tomorrow.

It's a bank2 sensor2 heater circuit. How old are your o2 sensors? No other codes?

LOL! That makes your comment about the throttle body make more sense.
