Code P0102 1997 Ford F150 Description

The P0102 diagnostic trouble code (DTC) for a 1997 Ford F150 indicates a problem with the Mass Air Flow (MAF) sensor circuit registering a low input. The MAF sensor plays a crucial role in the vehicle's fuel delivery system by measuring the amount of air entering the engine. This information is used by the engine control module (ECM) to calculate the appropriate air-to-fuel ratio for combustion. When the MAF sensor detects a low input, it means that the engine is receiving less air than it should, leading to potential issues with fuel delivery and engine performance.
