P0102 - Mass Air Flow ( MAF) Circuit Low Input Basically this means that there is a problem with the Mass Air Flow ( MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage ( air flow). TEST 3: Testing The MAF Signal Circuit So far, in your troubleshooting tests, you' ve confirmed that: The MAF sensor has power. The MAF sensor has Ground. With power, ground and air flowing thru' it, the mass air flow ( MAF) sensor has to produce a MAF signal. Description or check engine light code P0101 or P0102 mass airflow sensor. Also know as the MAF. Read what sets this code and some common causes and repairs.
