Code P0102 2006 Nissan Pathfinder Description

The P0102 diagnostic trouble code (DTC) for a 2006 Nissan Pathfinder indicates a problem with the Mass or Volume Air Flow Circuit, specifically a low input signal. The Mass Air Flow (MAF) sensor is a crucial component of the vehicle's engine management system, as it measures the amount of air entering the engine to determine the correct air-fuel mixture for combustion. When the MAF sensor detects a low input signal, it means that the airflow is lower than expected, which can lead to a variety of performance issues.
