check engine light

If I have really fixed the problem that triggered my "check engine" light, will the light turn off on its own, or do I have to reset something?

Unplug the battery for 20 mins.

Depends on what turned it on. If it was an unplugged MAF sensor, that will turn off in minutes by itself. It was a fugged up 02 sensor, that's not shutting off for a while. Every code has a number of start cycles the engine has to go through before the ecu clears a code on its own.

Just unplug the (-) battery cable for a little while and clear it manually. If you really did fix the problem, the light will not come back on.
