HAD THE CAR SCANNED INDICATED EGR VALVE NEEDS REPLACED. BUT IT DOES NOT HAVE A EGR VALVE SO WHAT COULD IT BE?
CHECK ENGINE LIGHT CAME ON on 2001 Kia Rio
Look under the hood of the car and read the Emissions Label. Does it say EGR anywhere for the emissions equipment? Also, make sure that you are having a professional scan done. Some people try to have a parts store scan their cars and this is very inadequate. Their tools are not a professional level tools and the person is not a professional tech.
