Ford Mass Air Flow (MAF) Sensor Diagram - Hot Wire, Cold Wire & IAT Thermistor

This document is a labeled cutaway schematic of a Ford Mass Air Flow (MAF) sensor assembly. It shows two views: a side cross-section (labeled "SECTION A") and an end-on view along section line A-A. The left view identifies the sensor's electrical connector and its signal designations — MAF RTN (return), MAF, and IAT — as well as the internal HOT WIRE (MAF SENSOR) and COLD WIRE (MAF SENSOR) sensing elements. Arrows labeled "AIR FLOW" indicate the direction air passes through the sensor body, and a SCREEN is shown at the inlet of the housing. The right view, looking into the circular sensor bore, points out the IAT SENSOR (THERMISTOR), which is integrated into the mass air flow sensor assembly. The illustration reference number A0071546 appears in the lower left corner. A reader can learn the internal construction of the MAF sensor, the location of the hot-wire and cold-wire sensing elements, the fact that the intake air temperature (IAT) thermistor is built into the MAF sensor, the connector terminal functions, and the correct orientation of airflow through the unit. No year, model, engine, part number, or specification data is stated on the drawing itself.
