O² sensor
An oxygen sensor, or lambda sensor, is an electronic device that measures the proportion of oxygen (O2) in the exhaust. It gives out a 0.1v - 1v signal depending on the oxygen levels present. If running well, it should be giving near enough to 0.5v, and switching above and below it, to aid in the removal of NOx (Oxides of Nitrogen), and CO's (Carbon Monoxide).
Unfortunately we were unable to perform our own tests on an O² sensor, but our tutor was able to give us an indepth demonstration on the workings of the sensor.
