Write down the code and any symptoms you notice.
Check the simple things first: the fuel cap, loose connectors and fluid levels where they apply.
Do not just clear the code. If the light comes back, the cause is still there and needs a proper diagnosis.
Read live data and freeze frame data with an OBD-II scanner app to see what the car was doing when the code was set.

DriveHub connects to a $15 to $30 OBD-II adapter, reads the code from your car and explains it in plain English. iPhone and Android.

General information, not a diagnosis. Causes vary by make, model and engine. If you are unsure, have the car inspected.
