A trouble code P0102 is triggered when there is low airflow registered by the Mass Air Flow or MAF sensor. Engine runtime over 2 seconds engine speed more than 300 rpm system voltage more than 10v throttle position less than 50 then the PCM detected that the MAF sensor input was 10 hertz or less less than 300 Hz on 74L condition met for over 250 ms. Before replacing the mass air flow sensor try replacing the air filter and cleaning the Mass Air Flow MAF sensor with low compress air or mass air flow sensor cleaner.

OBD-II Code P0102 is defined as a Mass or Volume Air Flow Circuit Low Input The Mass Airflow Sensor MAF measures the amount of air entering the engine and the Engine Control Module ECM uses the information to determine the proper amount of fuel quantity and ignition timing. This diagnostic trouble code DTC is a generic powertrain code which means that it applies to OBD-II equipped vehicles that have a mass airflow sensor. In order for the ECU to function properly the MFA flow rate must be within a preset range of values and if the MFA communicates a number too low the ECU wont function effectively.
