MAS replacement

In another thread I talked about how my Check Engine Electronics light came on several times. I took the advice offerred here to change my gas cap, and took it to Autozone to have the OBD2 code read. The code was P0100, and Autozone printed out the following for me : " The PCH has determined that a malfunction exist in the electrical circuit for the Mass air flow or volume air flow sensor. This code points to possible wiring problem, ie, short to ground, short to power, or an open circuit"

Do I need to replace the MAS? Is this a easy do-it-yourself job with no special tools or procedures to follow?
