Code P0102 2010 Nissan Pathfinder Description
The OBD-II trouble code P0102 in a 2010 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 ensure the proper air-fuel mixture for combustion. When the MAF sensor detects a lower than expected voltage signal, it triggers the P0102 code, indicating that there may be an issue with the air flow circuit.
