    OBD-II Trouble Code: P0102 Mass Air Flow (MAF) Circuit Low Input

    looks like your maf is bad, or maybe the wires leading to the plug for the maf are cracked or missing insulation. you can also try cleaning your maf with maf cleaner.

    It means there is something wrong with the mass air flow circuit. You need to check the wiring and if the wiring is ok replace the sensor.
