Check Engine light still on with code P0102

[Rajkumar]

I cleaned the MAF sensor. Ithink it was MAF sensor which is very close to the Ait filter. After cleaning also it didn't worked. I removed the battery connection for more than ten minutes the Check Engine light went off for some time than it came back on. Can anyone tell me the sensor I cleaned is the MAF sensor or some other. If it was the right sensor do I need to replace it. Is there any solution for the problem.
