If it is just coming on while you start the car and then going off while the car is running, that is normal. If it is staying on after the car is running, it could be that the cap to your gas tank is not completely closed. The cap has to click atleast 3 times when you close it. I have had this problem on mine before.
it has a problem
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.
How do i check the transmission fluid in a manual 99 Hyundai Accent?
disconnect the battery for about 30 sec then reconnect it
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...
go to your Hyundai dealer and make it check
check eBay
because you are one alot of ol timers call the check engine light and idiot light
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.
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.
