Also, does the dealership do those checks for free?

You should probably search for your problem or start your own thread. This one is too old I've already fixed this problem with my car.

The dealership doesn't do checks for free unless you are still under warranty. If your SES light is on you can check to see if your local auto parts store scans it. I know Advance is supposed to around here, but I have to go to the next town.
