Before you turn out the light you should have a code read carried out just to make sure nothing sinister is going on with the management system.
If the car is running ok then the code will probably either pertian to the O2 sensor, the EVAP system, or a drop in catalytic efficiency, but this isn't set in stone, just the most popular scenarios.
Very best regards

Reseting the cpu will clear the check engine code however it will not fix the problem that caused the check engine light to come on. The most common cause of failing emissions is the O2 Sensor. This sensor will trigger the check engine light when it is failing. The good news is that the Oxygen senser is pretty cheap and is mounted on your exhuast so it is fairly easy to replace yourself. I suggest replacing your O2 sensor the clear the computer by disconnecting the negative battery terminal and leave it disconnected for a few moments, hook up the negative again and it's all clear. Take your car back threw emmisions and you should be all set.
Hope this helps

replace your gas cap and clear codes, then wait and see if light comes back on, if it does you have a more serious problem like a fuel tank leak or a defective fuel tank pressure sensor.
