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.
Thank you for your response. It was very helpful.

SOURCE: Broken Hyundai 2002 Accent door handles
i have a 2005 hyundai both back doors would not open from the outside . after taking the panel off i found out that the handle is completely plastic and that it had broke in half because off stress . i removed the handle ( which was a pain ) and used quick drying epoxy on the crack . then i put a thin piece if aluminum on each side of the crack and used the same epoxy to hold it on . the next day i put the handles back on ( after letting the epoxy dry ) and it has worked perfect ever since. my next recourse , if it breaks again , is go to ebay . there is a seller if you type in hyundai door handles that sells 2 after market ones for $39.99. they fit 2001 to 2005 . i hope that this helps .

Under the hood, there is a fuse block. I believe it is on the driver's side of your vehicle. Open that box, and pull the "ECU" fuse. Leave the fuse out for at least 5 minutes. Put the fuse back in, start the car, and let it idle for at least another 5 minutes. Do not drive the car, touch the gas, or even look at the gas pedal for these 5 minutes, as the ECU is remapping itself. This will properly reset the ecu and clear the codes. After this you may drive the car.

It may be the computer itself. If the light keeps returning, either the computer is faulty or the fans are really failing. I do not recommend dealers but actual mechanic shops.

Resetting the computer is usually done by disconnecting the negative terminal on the battery for a few minutes then reattach.

You might check to see that the tire pressure is correct on all of your tires. Advance auto parts has a scanner they will loan you to clear this code yourself.
