Lambda oxygen sensor O2

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. Every one of our O2 sensors incorporates proven OE technology, for fast-acting, long-lasting performance. Industry’s fastest light-off 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. Given its position in the exhaust stream, O2 sensors are particularly vulnerable to contamination. A contaminated sensor can burn up to 25% in additional fuel and omit harmful emissions – it’s also one of the biggest causes of O2 sensor failure. To help prevent this, our O2 sensors feature an exclusive poison-protection coating which guards the sensor from contaminants, and reduces the risk of an early failure. Longer-lasting Water, vibration and extreme heat can also affect a sensor’s response characteristics. That’s why Delphi O2 sensors are fitted with a high-temperature water seal.
