1996 Ford Bronco 5.8L O2 Sensor Locations - Heated Oxygen & Catalyst Sensors

This is a screenshot of a page from Ford's Technical Service Publications service manual software showing heated oxygen sensor (HO2S) locations for the 5.8L engine. The main illustration (figure DA1663-A) depicts the exhaust system layout with callouts identifying the Heated Oxygen Sensor (part designation 9F472) and the Catalyst Monitoring Sensor (9G444). Two configurations are shown: the "49 STATE - OVER 8500#" (GVWR) application, which shows a single heated oxygen sensor location near the exhaust manifold, and the "CALIFORNIA/49 STATE - UNDER 8500#" application, which uses two heated oxygen sensors (9F472, "2 REQUIRED") upstream of the catalytic converters plus a catalyst monitoring sensor (9G444) downstream. Orientation arrows indicate "FRONT OF VEHICLE" and "FRONT OF ENGINE." A partial diagram at the top of the screen (figure A25143-A) shows the catalyst monitoring sensor 49-state location for a preceding section. A reader can learn where each oxygen sensor is physically mounted on the exhaust system of a 5.8L-equipped truck, how sensor count and placement differ between emissions calibrations (California vs. 49-state) and GVWR classes (over/under 8500 lb), and the Ford base part-number designations for the sensors. The file reference STJ3E041.GUI appears in the status bar; no model year is stated on the page itself.
