How can I remove false codes (check engine light ON + check engine electronics). I have procuded to do a TUNE UP and cleaned throttle body and I am convinced that the car has no more problem's, but the false codes are still there.
Any help?

What makes you think they are False codes??
Do you have these codes?

Because the problems have been taken care of. I still have the codes even though I've fixed the problems.

Same person that read your codes should be able to erase them ( with the same tool ).

If you fixed the problems that brought on the codes , the ECU memory would clear itself with a few drive cycles and self-test....or , you have not solved all the problems that brought on those codes.
So, a list of the codes will tell that................
