Code P0102 2011 Ford Fusion Description

The P0102 diagnostic trouble code (DTC) for a 2011 Ford Fusion indicates a problem with the Mass or Volume Air Flow (MAF/VAF) circuit having a low input. The MAF sensor measures the amount of air entering the engine to ensure the correct air-fuel mixture for combustion. When the MAF sensor detects a low input, it means that the airflow is lower than expected, which can lead to an incorrect fuel mixture and affect the engine's performance.
