The check engine light can be reset by disconnecting the battery for a few minutes. If it comes on again you should get the codes read with a OBDII reader. Autozone or another parts supply chain will usually do it for free. The codes are stored on board the PCM and will tell you where your vehicle is having a problem.
If the check engine light ever flashes then it is a do not drive situation.
