You would need to list all the codes you received so we could help you isolate the problem. You may have a more major issue that needs to be diagnosed. I recommend having a mechanic come and diagnose the Check Engine Light for you if you cannot find the problems. You should not drive the vehicle until the problems are diagnosed or you could more damage to the systems involved.
