Common reasons for a CEL?

My most common reason for getting a SES (or CEL) light is emissions related - either an O2 sensor going bad, or even something as simple as not having the gas cap screwed on all the way.
Either way, as the others have stated, any auto parts store should have a basic code reader to get the code for you.

i had this recently and found out it was a bad gas cap (a loose gas cap can trigger two lights, either the check gas cap light or a CEL). my cap was about 10 years old so just rpelaced with an OEM one, i had to reset the CEL though since those will not reset on their own.
in the end i bought a $20 bluetooth OBD2 adapter and an app on my android phone to reset the CEL. way cheaper then going to the dealer to reset the CEL.
the adapter is useful to have since it will read OBD2 codes for other errors

I had one when I first got my MINI (preowned), I believe it was "leak diagnostic pump", which I believe is part of the fuel system but I don't even know what it does. Diagnoses leaks I guess. ?
In my opinion, you should invest in an OBD2 device.
I have a Bluetooth one and I use it with my Android phone with an app called "Torque", which can actually display a lot of useful info about your car in real time (e.g. temperature). You can use it to reset your light as well, but it'll just come back after a couple of trips.

Obama a couple of years ago pulled all of the zinc out of oil and fuel that goes in cars. The zinc is a lub for older cars that don't have roller cams like all modern cars do. The reason that I mention this is that zinc is the one of the top reasons catalytic converters and O2 sensors go bad.
