Oxygen sensor - Wikipedia
WEBAn oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed.
Lambda, Lambda, Lamba: Understanding Oxygen Sensors
WEBAug 8, 2022 · An O2 sensor (not an AFR sensor) is only able to send basic voltage signals of rich or lean. When it sends either signal, the control unit reacts and adjusts the fuel mixture. So, for example, if it sees a rich signal, it will continue to lean out the mixture until it sees a lean signal.

WEBAug 28, 2018 · These sensors are referred to by several names such as lambda sensors, AFR, LAF and wideband O2 sensor. A wideband sensor can detect oxygen content in the exhaust that’s way below or way above the ideal air/fuel ratio of 14.7:1. More control of new lean-burning engines that emit ultra-low emissions is necessary today.
