As with any check engine light in an OBDII Vehicle (1996 and newer), use an OBDII scanner to FIRST read your codes and find out why it was on in the first place, then SECOND erase the code using the erase command on the scanner. If you don't fix the problem that caused the light to come on in the first place, it will always return.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
Repairing the fault which is causing the check engine light is the recommended way to go about doing this.
if you are talking about the check engine light and you have fixed the problem that caused it to come on in the first place, just disconnect either terminal from the battery and wait about 30 seconds before you reconnect it..
Without a code reader (you can buy one for about $80 at most auto parts stores), you can sometimes erase the codes by disconnecting the battery cables. Most newer code readers allow you to erase the computer memory.

To reset the check engine light on a 1994 Honda Civic locate the fuse box in the engine compartment. Find the ECU fuse and pull it off for at least 5 seconds. This will erase all codes on the ECU.
you can't do it agane
Disconnect the negative battery cable for a couple of minutes, then reconnect. This will erase the codes in the computer that makes the CHECK ENGINE light come on. If everything is okay, the CHECK ENGINE will stay off. Tried exactly that advice on my 2001 Camry....and it worked like a charm!!!
You fix problem first, then set tyour Code reader to "Erase code", turn on engine and check again .Sometimes it takes 2-3 starts to erase.
Disconnect the battery for 5 minutes or use an error code reader to erase the computer to the default configuration.
if it's 96 & newer.. you will need an OBD2 scan tool to erase the codes that turn the light on.
