HI there! This is a code for the converter. The only repair is normally replacing the converter. I would first contact the dealer however. Give them your VIN and see if there are any reacalls or bullitens that apply. Also, the converter is covered with a 8yr/80k mile warranty. If you are within these limits they will have to replace it free of charge. Hope this helps! Thanks
