Read your owners manual!
If it's red stop as soon as possible, and get someone to assess the problem. Read the code etc.
If it's yellow the problem will likely just degrade the car's performance, and it won't pass inspection if that's a concern. Get the problem assessed as soon as you can, becase it will get worse.

If the check engine light it on a 2002 Hyundai Accent on one of the sensors is malfunctioning. The computer is acknowledging this and alerting the driver that there is a problem in the engine.

No, the check engine light means there is a problem with the emissions system. The maintenance required light means something like an oil change needs to be done.
When my check engine light comes on, it is caused by the temperature sensor not working. As soon as the light comes on, my temperature drops to cool. If the light goes out, the temp gauge returns to normal.
Probably need to check the crank sensor (if the check engine light is on) or the fuel pump... I had that problem not too long ago...
A blinking or flashing check engine light in any Hyundai is indicative of a misfire taking place. It could be due to a faulty ignition.coil, leaky ignition wires or bad or worn spark plugs.
I have a 99 Hyundai Sonata That the check engine light came on, and # 3 & 5 Injectors were fouled
No the check engine light will not come on
The check engine light, on your Hyundai Elantra can be reset by removing the fuse. Keep the fuse out for 10 seconds and replace it to its slot.
