Answers :

The check engine light is an early warning system to protect your engine from malfunction. There are several sensors within your engine that trigger this light. If you have your owners manual there will be a section in it that tell you what to check. The basics are ;
engine oil level
coolant level
blocked air filter
but the list can go on so look at the manual.
