how do I reset the check engine light?

My check engine light came on but the car is still running fine.
I think it just tripped a sensor or something.
I was thinking just reset it and see if it happend again.
Trying to save a trip to the dealer just to have them reset it.

thanks

Disconnect the negative terminal of your battery, wait a bit, and reconnect it.

Thanks
Do you agree that I should blow off the light the first time it happens if the car still runs mint?
If it trips again I would take it in.

Do you have any mods? It could have been something silly like moisture on the MAF. Reset the ECU like stated above, and if that doesn't make it go away (after you drive for a few miles), it's time for a trip to the dealer.

no mods yet..... :P
I was thinking that it was somthing silly like that or just getting on the car hard before its warmed up.
Tripping a sensor of some kind
I live right off the highway and had to jump on it pretty hard right off the bat.
Guess I will reset it and if it doesn't come back....we are allll good...

thanks
