Ford Bronco EGR Valve Position (EVP) Sensor Connector Pinout Diagram

This scanned manual page shows a connector pinout diagram for a Ford EGR Valve Position (EVP) Sensor, uploaded to the gallery of a 1991 Ford Bronco. The illustration depicts the face of the three-pin sensor connector mounted on top of the EGR valve, with each terminal identified by a callout arrow: VREF (reference voltage) on the upper-left pin, EVP (position signal output) on the right pin, and SIG. RTN. (signal return/ground) on the lower pin. The diagram is captioned "EGR VALVE POSITION SENSOR." Fragments of surrounding diagnostic text are visible at the top of the page, mentioning "100 ohms" and instructions to "service the" or "replace the" a component, indicating this figure accompanies an EVP sensor testing procedure (likely resistance/voltage checks), though the full test text is cut off. A reader can use this diagram to identify which terminal is which when probing the EVP sensor connector during diagnosis — for example, to check reference voltage on VREF, signal output on EVP, and continuity to ground on SIG. RTN. No year, model, engine, wire colors, or part numbers are visible on the page itself.
