Answer
Hi Matt,

 A P0101 is a MAFF sensor code. The MAFF sensor measure the the incoming air and translates it to a Grams per second reading so the computer knows how to manage the fuel ratio.
 You could remove and clean the MAFF sensor with air system intake cleaner.  It is not always recommended to clean MAFF sensors but you are setting a code anyways so it wouldn't hurt.  If you clear the code and it comes right back it is most likely the MAFF sensor that is the problem.
