O2 sensors measure oxygen levels in your exhaust fumes to gauge engine 'efficiency'.
Gas engines work by combusting an air-fuel mixture in the engine cylinders. This mixture needs to be burned at a precise ratio to perform as efficiently as possible. If this ratio is off, the mixture in the engine is considered 'rich' if there is not enough oxygen in the mixture, or 'lean' if there is too much oxygen - both of which can cause harmful emissions and potentially damage your engine.
