Do you have a cell phone? Is it an android? Then you can get your own scanner cheap right on your phone with the Torque Pro APP and a blue tooth USBII port scanner for less than $20.

I even ordered a spare one last week because they have become so cheap.

If car's running fine, in most cases, the check engine light's on due to some faulty sensor (emissions), or vehicle threw a code fm malfunction. If you don't have the means to self-scan, take car to auto parts/auto repair and they can scan for diagnostic codes. Pretty much any/all vehicles are run by computers so without the codes you're shooting in the dark.
