Hi, I just bought a 2009 Murano. (By the way, what exactly does MO stand for?)
My Service Engine Soon light came on a few days ago and I'm thinking that it was AFTER I got gas the last time. I left the engine running as my friend always does in her charger (I've never done this before but it was outrageously hot outside here and she was in the car so I left the air on for her.) I turned the gas cap to 2 clicks. After reading this forum for a bit, I'm guessing the SES light may have come on because I left the engine running while pumping gas. Does that sound valid?
First, why exactly would that cause that? (I like to know how stuff works - not just be told by someone not to do something. I want to know why.)
Second, what's the easiest way to clear the light so I can see if that was actually the problem?
If it comes back on it probably wasn't, possibly.
Thanks y'all!

You are aware that leaving a vehicle running while filling it is illegal, due to the (minimal) risk of static electricity causing fire or explosion...? Having the gas cap off is a giant air leak, but the light should clear in a few miles of driving.

Mo = MuranO
