I own a 2001 tiburon and checked my owners manual. The light is the malfunction indicator light (MIL). It uses a sensor in the exhaust system to detect when there is a change in the composition of the exhaust gases. The MIL is pretty good at catching "little" things wrong with your engine so if your experiencing any change in engine power or in fuel economy I would recomend you have your tiburon checked out.
yes
Take your car to an AutoZone and ask them to pull your codes. They offer this for free, and it will reset your engine light, and you'll get to know why the light was on. Until you actually fix the problem though, the light will just come back on.
Usually low tire pressure - usually from cold weather.
If you fix the problem causing the light to come on, it will go off.
I have a 99 Hyundai Sonata That the check engine light came on, and # 3 & 5 Injectors were fouled
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.
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.
your question makes no sense. the imobilzer would be if you disconnected battery.it shouldn't matter if you replaced it with a 04 engine. unless you have a bad crank position sensor. or a bad ignition switch for security.
No the check engine light will not come on
check you grounds and the alternator
this means that either your exhaust/gas value isn't working properly or a bad senor that can be replaced if your under warranty or can pay about 100.00. but unsure if Hyundai acts like Honda in a way that the check light is program to go off just as a check method for the car and as a reminder.....hope this helps Don't believe last answer is correct, if you meant "O/D off" indicator light is on, then it means your overdrive is turned off, I have a 2001 Tiburon and there is a button located on the my shifter that allows you to turn the overdrive on and off.
