Dear Rkesbia,
You don't give the code meanings. I cross referenced the codes with a different model and all the codes lead to the Evap system malfuntion. You didn't give the miles on the vehicle so assuming the car is fairly new and still under warranty. Check that the gas cap is tight and has no cracks in it. Clear the codes and if they come back check with the dealer to see if it is still under warranty and have them fix it. ( Emmission controls are warranty 5 years )If not then you will have to trouble shoot the Evap system. Start with the gas cap then the hoses wires etc. Hope this helps

I do know for a fact that there has been a Technical Service Bulletin regarding certain evap codes which require th PCM to be reflashed or replaced, as well as the catalytic convertor and O2 sensors. Unfortunately, it's only covered by the manufacturer if it happens before I believe 5 years or 80,000 miles.
