Abstract

Volkswagen error code P0101 indicates a problem with your mass air flow (MAF) sensor circuit, which measures the amount of air entering your engine. This sensor helps your engine computer determine the proper fuel mixture, and when it malfunctions, you may experience poor acceleration, rough idling, or reduced fuel economy.
