My wife's 09 Pure with just under 13k, threw a CEL today. The code was P2178, system too rich. I erased the code, drove the vehicle & everything is back to normal.
Prior to the CEL coming on, the car was shifting abruptly and harsh. It didn't turn on the CEL until the end of the trip, which was about 30 minutes. The car also seemed to hiccup slightly around 70 mph.
About a month ago, I had the harsh shifting symptoms, but no CEL. I disconnected the battery for 30 min. & after reconnecting, everything was fine.
Has anyone had any experience with the code? I kind of suspect the evaporative emission control system. Please note that when I refuel, I fill on automatic and once the nozzle shuts off, I do not top off.
Your input would be appreciated.
Thank you,
Bob
