Code P0102 2004 Nissan Maxima Description

The P0102 diagnostic trouble code (DTC) for a 2004 Nissan Maxima indicates a problem with the Mass or Volume Air Flow Circuit Low Input. This means that the engine control module (ECM) has detected a lower than expected voltage from the mass air flow (MAF) sensor or circuit, which is responsible for measuring the amount of air entering the engine. This can lead to incorrect air/fuel mixture calculations, affecting engine performance and emissions.
