Question about 1999 Hyundai Accent

1 Answer

Check Engine Light

I have 120,000 miles on my 1999 Hyundai Accent and the check engine light has come on.

It probably means that I should have something serviced, but what?

I would appreciate any help you can give me.

This is because there is a leak in the muffler and this light indicates increase in oxygen detected by lambda sensor... so nothing serious but you might be injecting little extra fuel causing little decrease in mileage... to fix this just replace or weld the muffler or most probably the flex pipe

I just took my Hyundai 2002 Accent to get inspected. The emissions test light would not come on. Mechanic said it would have to go to the dealer to get the computer reset. Does this cost a lot?


There not exist any computer reset that correct a emission out of range. If the car is running without the check engine light comes lit ( it means if you drive the car more than 40 miles and the check engine light remains off) and the emissions are out of the range, is necessary check if the engine is operating in normal coolant temperature ( half way to the top), check if the air filter is free, check for the spark plugs are working properly, and check if the catalytic converter is at least in 13% of CO2. Also check with a scanner tool if have any engine code stored in the memory.

Both the check engine light and the airbag light have come on


The two lights you mention are also two separate systems in the vehicle. There is always a code set when the Check Engine light comes on. Find an OBDII scanner & scan the ECU (Engine Control Unit) to find any codes. I need to know which code(s), there may be more than one. The Airbag light is a proprietary (Hyundai specific) system with unique coding. That particular system can only be diagnosed by a qualified Hyundai Technician and the appropriate scan device (Hi-ScanPro). Check with your nearest Hyundai Dealership... I doubt that 1999 Accent is still under warranty.

Some cars do this as an indication they need to go to a garage to be serviced. You should have the car checked for the cause of the oil leaks.

I have a Hyundai Accent (1999 with 70k miles. I replaced timing belt and water pump at 65 k miles and in general car was running fine except that the check engine light was on. I was driving on highway...


Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there.

99 hyundai accent starts sometimes. not battery


ok when the check engine light comes on that usually indicates a engine malfunction...what you can do is go to your local autozone and they can do an OBDII test for free..my bet says it is the cam or crank sensor.. DO NOT SHUT THE CAR OFF AT AUTOZONE..LOL
