Most independent service centers will read the code for you.If you are lucky,it might be something as simple as the gas cap.If you are handy at all with tools,download the instructions,go to
ebay,buy the handle and replace it yourself.I had never replaced one until last week,needed a couple of tools and just over an hour to take it apart,replace it and put it back together.And the handle was $39.99 plus $6 bucks shipping from
garrickwholesale760. Good luck.
