Oxygen Sensors And Wide-Band Air/Fuel Ratio Sensors

VIDEO: Wide Or Narrow? What Is The Difference Between Oxygen Sensors And Wide-Band Air/Fuel Ratio Sensors?

In this video, Andrew Markel explores the difference between the two types of oxygen sensors and how the ECM sees the amount of oxygen left over after the combustion cycle. He also explains how new technology allows modern engines to see more of the fuel trim of the engine.
