While I am in no way a mechanic, I can tell you that I had this problem before. The first thing I did was to make sure my Gas Cap was on tight. If your gas cap is loose, the "check engine" light will come on after a while. After about 150 miles, the light went off. I think it has something to do with re-setting the sensor...Hope this helps.
I have a 99 Hyundai Sonata That the check engine light came on, and # 3 & 5 Injectors were fouled
It appears that if you disconnect the battery for 5 seconds you get your reset.
Answer: Replace Hyundai Sonata.

I have a 2000 Hyundai sonata, and I read in the manual that the air bag light comes on when it is time to have them serviced or checked. Also, check out sonata recalls. I have heard of some recalls concerning air bags on sonatas.
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.

You can check the Hyundai site... www.hmaservice.com... Sign up and there is a wealth of information on it. I just replaced my cam shaft position sensor on my 1999 Hyundai Sonata 4 cyl 2.4.

There must be a "check engine" light on. Start with investigating the DTC's (Diagnostic Trouble Codes).
