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.
