I went to a garage to have the codes checked and the mechanic was unable to tell me what the codes meant. He said I would have to go to Hyundai to tell me... I cehecked dmy gas cap, it's ok. He re-set the sensor to see if the check-engine light would come right back on... it did. I'll go to Hyundai to see what is going on. Thanks for oyur response.
