The check engine light is an immediate signal to pull into a garage and get a quick diagnostic check. It could be a variety of problems with the engine. Usually there is a separate oil light or a wrench icon on newer vehicles to indicate an oil change is required.

Check the bulbs first. This is usually an indication of a bad bulb. If all the bulbs light, turn on the headlights and check again. The bulb that won't light has no ground connection. With the headlights off, the circuit was completed through the headlight. The turn signal switch might also be bad. But the flasher is good, since it works on the left.
The check engine light is a signal from the computer that there is a potential problem that must be addressed. When the light comes on it is a signal that the computer has stored a problem code that you can read using a code scanner. You can borrow, rent or buy one at most auto parts retailers.
A check engine light on a 2001 Honda Civic means there is a malfunction occurring somewhere on the engine. The ECU is sending a signal so to make the driver aware of the situation.
As previously said. Dead, or weak battery. The light you're talking about is a blinker signal light, not a check engine light. It's just coincidental.
First thing is to check for a burnt out bulb in either the front or rear turn signal for the side that stays lit. Second, if the bulbs are fine then check for a bad turn signal fuse/cannister. Hope this helps.
