SOURCE: MAAS AIR SENSOR

A mass air flow sensor is used to find out the mass of air entering a fuel-injected engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature and altitude, and this is an ideal application for a mass sensor. (See stoichiometry and ideal gas law.)
There are two common types of mass airflow sensors in usage on gasoline engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with an additional sensor or two, the engine's air mass flow rate can be accurately determined.
Both approaches are used almost exclusively on electronic fuel injection (EFI) engines. Both sensor designs output a 0 - 5.0 volt or a PWM signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature (IAT) sensor incorporated into their housings.

    2008 Chevy Kodiak c4500 duramax desiel code reader (Innova 3100 Can OBD2) shows P0102, what does it mean


    P0102 Chevrolet - Mass or Volume Air Flow Circuit Low Input

    Read more: http://engine-codes.com/p0102_chevrolet.html#ixzz38p5k1ZD8

    Possible causes - Faulty mass air flow sensor
    - Intake air leaks
    - Dirty mass air flow sensor
    - Dirty mass air filter
    - Mass air flow sensor harness is open or shorted
    - Mass air flow sensor circuit poor electrical connection

    Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
