Mass flow sensors measure air mass entering fuel-injected engines. Air density varies with temperature, altitude and forced induction. Both vane meter and hot wire are common types used in EFI engines
Produce sinusoidal voltage signal through magnetic pickup effect. Coil resistance ranges from 200 to 2,500 ohms. Output voltage typically 1-2V during engine cranking. Signal wires shielded with coaxial coating
Multiple wiring diagrams manuals available for different Ford Transit models. Manuals cover electrical systems from 1970 to 2019. Diagrams include grounding, fuse, and component locations
