oxygen sensor O2
Delphi Power Train
The oxygen sensor, otherwise known as an O2 sensor or lambda sensor, measures the amount of oxygen in the exhaust. Whilst this may sound like a fairly modest task, the O2 sensor is actually one of the most important sensors on any vehicle, responsible for maintaining a harmonious balance between air and fuel for optimal emissions. Too much fuel produces hydrocarbons and carbon monoxide. Too little fuel produces nitrogen-oxide pollutants. The O2 sensor helps keep this mixture just right. Because of this you’ll want to fit a quality OE brand, such as Delphi Technologies. Every one of our O2 sensors incorporates proven OE technology, for fast-acting, long-lasting performance.
Since the majority of hydrocarbons and carbon monoxide emissions come within the first 30 seconds after a cold start, fitting a fast-acting oxygen sensor is critical. Our planar sensor element with integrated heater, reaches optimum operating temperature in a matter of seconds – as quick as six seconds to be precise – for quicker closed-loop activation and reduced cold start emissions.
