SES light turned on on 2000 Infiniti I30

usually does the service engine soon light turn on because of the MAF(mass air filter)? or is there another common reason why the SES warning light would turn on? should I be worried about it? is it covered by warranty?

MAF stands for Mass Air FLOW sensor. You need to go to a Advance or Autozone parts house and ask if they would scan your car. Make sure you get the codes, not what they think you need. The codes will look like P0000 something.
Yes the SES light will come on when Any sensor has failed or has been unplugged or in any way not doing what it is designed to do.
