Ford 5.0L/5.8L Air Throttle Body Assembly Diagram - Canister Purge Ports & TPS

This is a scanned page from a Ford service/reference manual describing the air throttle body assembly used on 5.0L and 5.8L EFI engines. The text lists three additional features of the assembly: a preset stop to locate the WOT (wide open throttle) position, a throttle body mounted throttle position sensor, and canister purge port(s), two on the 5.0L engine and one on the 5.8L: used for evaporative emission control. Item 3 and the corresponding diagram callout are highlighted with red circles by the uploader, indicating focus on the canister purge ports. Below the text is a labeled line drawing of the air throttle body assembly (figure reference V8035-1A) with callouts identifying the throttle plate set screw, air bypass valve idle speed control, throttle position sensor, and the canister purge ports on the 5.0L version. A reader can learn where the canister purge ports, TPS, and idle air bypass valve are physically located on the throttle body, and that the number of purge ports differs between the 5.0L and 5.8L engines. The page was uploaded to a 1990 Ford Bronco gallery alongside other 1990 emissions-related diagrams.
