I have a 2005 Elantra with 1600 miles on it and the check engine light stays
on. At first I thought it was the gas cap thing, opened it and closed it.
Light went off after a few starts, then came back on. Went to the nearest
dealer (not where I bought the car), they said the electronic control module
was bad. Part was supposed to be overnighted, but it was on backorder.
They got the part in, it was wrong. The dealer actually gave me a loaner.
They fixed it, I picked up my car on Thursday. Then on Friday the light
came on again and has stayed on. I called the dealership and they will look
at it whenever I can get there.

The car is running fine, and other than this issue I love my car. What can
the problem be???

Could be just about anything. Hyundai recently released a booklet
describing its diagnostic trouble codes and descriptions. The section
involving things that could trigger a check engine lamp is 36 pages.

As said earlier it could be many things so you'll hve to leave it with them
for some time to get to the bottom of it.

i have a 2004 elantra and my check engine lite (after a few fail
fixes) was (so far) a DPS sensor.. I think that stands for distributor
position sensor..

There's no distributor on your car...could you dig up the receipt and
tell me the Hyundai part number of that part? Thanks.
