It is usually indicative of the E.G.R. Valve (Exhaust Gasoline Recirculation Valve). Is your gas mileage way down? I Had E.G.R. Valve replaced and the light no longer comes on. Good luck. Thank-you for sharing.
First, you need to fix whatever's wrong, then you unhook your battery cable for about 30 minutes, then re-hook. If it comes back on, you have a problem that was not addressed.
You select TRIP A on the odometer. Turn the key off, hold down the select button on the odometer (the one you used to select TRIP A)... while the car is off, then turn the key to on. Here is a video of the procedure:\nhttp://www.youtube.com/watch?v=vj7kK5i2tPc&feature=related

Evap control systems are often times difficult to diagnose. Try using information here:. http://www.gearchatter.com/viewpost17788.php. If that is more than you want to deal with you may want to take it to a good mechanic.
You may have a faulty engine light. Or, you may have a seriousproblem with your car. You should take your car to a local mechanicfor diagnostics.
Answer . \nThe problem is, you haven't used a code scanner yet. The code scanner will tell you the rest of the story. Borrow, rent or buy an OBD2 code scanner at your local auto parts retailer. Many auto parts retailers will even help you use it and figure out what it all means.
Try disconnecting the positive battery cable for 3 to 5 minutes, replace. If you have serviced the engine and all levels are good this should reset the computer chip that controls this light.

In the absence of any other problems (such as lean running condition, worn or non-iridium spark plugs, or damp weather) expect an EGR valve stuck open or a faulty MAP sensor.
Many cars will keep a history of any codes that have been tripped since the last time the codes were cleared. Once codes are cleared by a scanner they are erased permenantly.
Answer . \nHave the cars cooling system tested at a reputable shop . The test you want to have done is a LEAK DOWN test which will give you a good idea where this problem is. Often this problem is due to a leaking head gasket.
Answer . \npo 302 is not a valid code but maybe misfire code number 2 cylinder
To many variables/year/model /auto or standard/describe light thats on/were their any problems leading up to this, or maybe the exhaust brake is stuck on, or maybe you have ignored your regeneration light on a newer model.
Chances are it is the transmission control unit (TCU). You should probably take to a qualified / reputable shop and have it scanned to be sure. I believe that auto repair stores (Advance Auto, Auto Zone, O'Reily's also offer free computer scans - if they have the hook-ups for that age of vehicle.
if it runs sluggishly and dies when you "punch" it - like to get out in front of traffic, good chance it's the timing belt. Hyundai uses a "toothed" belt for timing and not a chain as in alot of other vehicles. the timing belt controls the rate at which the pistons fire in conjunction with the fuel...
Go to the local Auto store and ask them to read the codes for you. They can tell you what the codes mean and what part to buy. You can also look the codes up online.

Have vehicle scanned to determine the problem - usually in the emission control system,
With out knowing what code you have set, that question can not be answered. Some codes can be caused by failures that can be damaging to the engine.
impossible. Truthfully, this was a stupid question. If you had a time machine judging by the questionyou asked and the way you wrote you'd probably cause it to explode. We are CENTURIES away from figuring out the fabric of time and space for now time machines science fiction.
Usually a problem in the emission control system - have vehicle scanned to determine the problem
This sounds like a misfire. The computer recognized this as a potential fatal problem and it is not. I would have the plugs and wires checked....have Autozone run diagnostics on your car and the specific cylinder will be identified. Good Luck
Hi, I was told that if you fill the gas tank while the car is running, the check engine light may come on, it will go off after a while of driving. I had the same intermittant problem.....

Bank 1 is usually on the driver side of the motor and bank 2 is the passenger, sensor 1 is the one on the header and sensor 2 would be after the catalytic converters. Bank 1 is the same side as cylinder #1.. Bank 2 is the other side.
At key on it should come on for a couple second "bulb check".
Trouble codes . Too many things to list. Take it to Autozone or some place similar and they will most likely read the computer trouble codes for free and you can have a better idea of where to go from there.
Cars now days are funny. Any little thing not right in the massive amounts of sensors will throw a check engine light. Have the vehicle brought to your local AutoZone for a free diagnostic check. It could be something as simple as the gas cap is not on tight. AutoZone will check it out for free.....
you'll need to fix your base timing.(try with a timing light) I don't believe that you can do this with a timing light, in this model this is all accomplished with sensors and the best source of information to do this is on the Chilton's website, it will be free through the library database. If you...
