How to Reset Check Engine Light?

The only safe way to reset a check engine light is to hook your vehicle up to an on board diagnostic computer and find out what problem is causing the light to come on, and then fixing the problem, the light can then be reset. You can temporarily reset the light by removing the battery for a few minutes, however, if the problem is not repaired the light will come on, and resetting it this way is also illegal in some states.
