The "Check Engine" light, or "Malfunction Indicator Lamp" in modern cars is activated when a fault is detected in the fuel delivery, combustion, or exhaust emission system of your car. Sometimes, the cause of the fault will 'go away', and the light will go out on its own. There is very little that is 'owner-diagnosable' about an MIL light, without the correct scanning and diagnostic tools at a qualified mechanic shop. Every car is different, but usually things like low oil pressure or a busted headlamp will not set off the "check engine" light.
