Air/Fuel Wideband vs Oxygen Sensors (O2 sensors)- The Demise of Shadetree Mechanics? Part1

In this video you will join me in learning about the new Air/Fuel Sensors (AKA Wideband O2 Sensors) used on vehicles today which replace the traditional Zirconia Oxygen Sensors. Understanding operation, how to diagnose sensor faults, and how to interpret outputs are covered with the intended audience being shadetree/home mechanics or serious hobbyists who want to increase their evidence-based diagnostic skills and not make 5 trips to the parts store when they try to fix their car!
