Hi XXX XXXXXX;
Here is a snippit from this web page

P0101 OBD-II Trouble Code
Technical Description

What does that mean?
Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds.

Symptoms
You will likely not notice any serious drivability problems, although there may be symptoms.

Answer

Ron;
If you have checked the items as recommended by the site linked above then yes change the MAFS.
As these are fairly costly I would hate for you to purchase a new one and end up finding out that it was a $25.00 O2 sensor.
Doesnt hurt to be sure at least.
Thank you for the accept.
