That is a Mass air flow sensor code. Try removing it and clean it with CRC MAF cleaner and reinstall and see if the light goes out or clear the codes afterward. If that doesn't work, then maybe the sensor itself has failed. But check the wiring next, there could be an open, shorted, frayed, poor connection, etc. in the wiring.
