It is a MAF error. While it could be the sensor, I would use a MAF cleaner to clean the sensor, only $7 and many times the sensor gets debris on it that affects sensor output.
This should always be the first thing to do, MAF sensors are expensive and as I said many times cleaning will fix it.
Ask around about a mechanic, find an ASE certified tech. Some do work on the side.
