Wideband Sensors vs. Narrowband — Understanding the Differences

One of the main reason’s manufacturers are going to wideband AFR sensors is because the heater channel comes up to operating temperature quicker — as fast as 10 seconds, in some cases. However, wideband sensors also need to be heated to higher operating temperatures to function effectively.
