In my 2005 honda accord check engine light come on i went to mechanic and he reset the light after few days light come agian

Your check engine light means that your computer thinks that there is something wrong with one of your systems. It is producing a code for the problem, but you can not read the code unless an OBD-II scanner is plugged into the OBD socket under your dashboard. Autozone, or another of the same sort, would be happy to hook their scanner up to your car and tell you what the computer is saying is wrong. There is not charge.
Hope this helps you.
