Most likely the cause is a loose wire somewhere in the car's wiring harness related to the computer system that operates all of the sensors that operate on the car's engine. I had a 95 Elantra, love it went great, cheap on gas. Butone day the check engine light came on and then never left. It was always on, no apparent problems though then and 3 month later the car took fire. Total loss. Dont know if related but that's my story....
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.
No the check engine light will not come on
take it to autozone and they'll tell you fro free
The computer has detected a problem with the emissions system. Take it to a professional.
It means there is a problem with the emissions system. Seek professional help.
Check the battery in the remote.
Water in fuel? Have vehicle scanned to determine the problem
the check engine light comes on for many reason or many parts usally emmision related.
Does the 2007 Hyundai Elantra have a power steering pump? How do I check the fluid level? How often should it be replaced? Thanks.

A simple way to check the air conditioning on a 2003 Hyundai Elantra is to turn on the unit in a car. If the air will not blow cold or at all the an the AC system will need to be looked at.
