Is an air fuel ratio sensor the same as an oxygen sensor?

Is an air fuel ratio sensor the same as an oxygen sensor? An air/fuel sensor can read a much wider and leaner range of fuel mixtures than a conventional O2 sensor. That’s why they’re also called “wideband” O2 sensors. An A/F sensor, by comparison, produces a changing current signal that varies in direct proportion to … Continue reading Is an air fuel ratio sensor the same as an oxygen sensor?
