Ford Idle Air Control (IAC) Valve Diagram - Cutaway Schematic & Airflow

This document is a labeled schematic of a Ford Idle Air Control (IAC) valve. On the left is a three-quarter perspective illustration of the complete valve assembly, showing its electrical connector, solenoid body, and mounting flange. On the right is a cross-sectional (cutaway) diagram of the valve identifying its internal components. Labeled parts include the solenoid (the coil section that actuates the valve), the diaphragm, the valve body, and the vent/filter, with a note that the vent/filter location may vary between versions. Arrows in the cutaway indicate the air flow path through the valve: air enters at the AIR FLOW INLET at the bottom of the valve body and exits through the AIR FLOW OUTLET. A reader can learn the general internal construction and operating principle of the Ford IAC valve, an electrically driven solenoid moving a valve within the valve body to meter bypass air, and can identify the external appearance of the part for locating it on the engine. The document contains no part numbers, year ranges, engine applications, torque specifications, or electrical pinout information; it is purely a component identification and airflow schematic.
