Code P0104 2018 Ford F150 Description

The diagnostic trouble code P0104 for a 2018 Ford F150 indicates a problem with the Mass or Volume Air Flow Sensor 'A' Circuit being intermittent. This sensor plays a crucial role in measuring the amount of air entering the engine to ensure the proper air-fuel ratio for combustion. An intermittent issue with this sensor can lead to inaccurate readings, causing a variety of performance issues in the vehicle. The Engine Control Module (ECM) uses the data from the Mass Air Flow (MAF) sensor to adjust fuel delivery and ignition timing, so a fault in this circuit can result in poor engine performance, reduced fuel efficiency, and even stalling.
