ymerameha Report post Posted November 26, 2022 Hello forum! I'm having a bit of trouble interpreting the wiring diagrams. Which heated oxygen sensor wire on the diagram is the signal wire? VS+? Is there somewhere the meanings of these abbreviations? What do the rest of the wire abbreviations for this sensor mean? Many thanks in advance to those who answered. Since I don't know much English myself, it's quite difficult to figure out what these abbreviations mean. Share this post Link to post Share on other sites
