you have to have fixed whatever set off the light to begin with or it will just come on again. easiest way is to take it to an autozone or similar place and have them throw the scanner on it. if you really need to turn it off you can unhook the battery for a minute or so and then hook it back up, just make sure you have your radio code.Hi all. Have done a search on this site and cannnot find a thread that tell one how to reset the check engine light. I know i found it on this site before, and have to take my E in for an e check in a few days. Any help would be appreciated.
