This code can be a nightmare to find. For me it was in time and money. Since it is specific to the MAF sensor, it can only be so many things. At the end of the day, it was a small vacuum leak in the lower air intake hose beneath the MAF sensor, a flex hose, that is prone to problems with age. The upper hose that has the MAF was fine.
The lower part ($150) is 3C0-129-565-B. This is actually a long plastic tube in one section and a short flexible part. It is the flex part that commonly gets a leak from a small hole (as in my case) that triggered the P0101 code. The name is Intake air tubing for use in cold weather countries.
The title forces me to ask: what does it do? does my car still need it even if I am in California? The car was originally in Colorado, which is way colder. If I do not need it, can I remove it and block off the connection ends?
