Answer Depends on which vehicle but a sure fire way to extinguish the MIL malfunction indication light is to have the codes read and re-set by the use of a diagnostics machine If you know why it came on, you can simply disconnect the negative cable from the battery. Make sure your radio doesn't need a code for anti theft. Reconnect in 30 minutes, if problem was caused by something that was minor and fixed out of a repair center, it will go off and stay off.
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.

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.
if it's 96 & newer.. you will need an OBD2 scan tool to erase the codes that turn the light on.
