Here is a list of possible diagnostic trouble codes associated with the MAF/MAP sensor:
P0100 Mass or Volume Air Flow Circuit Malfunction
P0101 Mass or Volume Air Flow Circuit Range/Performance Problem
P0102 Mass or Volume Air Flow Circuit Low Input
P0103 Mass or Volume Air Flow Circuit High Input
P0104 Mass or Volume Air Flow Circuit Intermittent
P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
P0106 Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input
P0109 Manifold Absolute Pressure/Barometric Pressure Circuit Intermittent
I would expect to be in the P0100 to P104 range. The MAF sensor is fairly reliable. The first thing I would do is check the electrical connector to make sure it is making a good connection. The sensor element can be contaminated by oil from a new cone style oiled air filter. The sensor can be cleaned with an aerosol specific for MAF sensors that can be purchased from you local autoparts store. Do not touch the sensor as it is fragile. Just spray it and let it air dry. If you clear the DTCs and neither of the above help then check the wiring to the MAF sensor for broken or shorted wires. The last thing to do is purchase another MAF sensor.
