O2 sensors play a vital role in detecting the oxygen concentration in exhaust gas and providing feedback to the ECU*1.\n\u003cbr\u003eNTK O2 sensors detect the oxygen concentration in the exhaust gas and provide feedback to the ECU so that the fuel-air mixture ratio (air-fuel ratio) reaches the optimal stoichiometric air-fuel ratio of \"λ (lambda) = 1*2\". Based on the signals from the O2 sensor, if the fuel is too rich relative to the stoichiometric air-fuel ratio, the ECU leans the fuel mixture; if it's too lean, it enriches the fuel mixture. This control ensures operation near the stoichiometric air-fuel ratio, where harmful substances in the exhaust gas are most effectively purified. Thus, NTK O2 sensors are crucial components for reducing harmful substances in exhaust gas.\u003c\/p\u003e\n\n\u003cp\u003eSpecifications\n\u003cbr\u003e【Features and Structure】\n\u003cbr\u003eZirconia elements have the property of generating electromotive force due to differences in oxygen concentration at temperatures exceeding 300°C. Utilizing this property, zirconia-type sensors detect the difference in oxygen concentration between the inside and outside of the element (atmosphere and exhaust gas) and feed back to the ECU whether the fuel is rich or lean relative to the stoichiometric air-fuel ratio.\n\u003cbr\u003eWide-range air-fuel ratio sensors can detect how rich or lean the mixture is relative to the stoichiometric air-fuel ratio. Therefore, more precise engine control is possible compared to zirconia O2 sensors. It also enables engine control outside of the stoichiometric air-fuel ratio (λ=1), such as lean burn control. Furthermore, some early activation wide-range air-fuel ratio sensors maintain the characteristics of conventional wide-range air-fuel ratio sensors while improving heat resistance and durability, and feature an integrated element and heater structure for early activation (operation starts within 5 seconds after the engine key is turned ON).\n\u003cbr\u003e【Necessity of Replacement】\n\u003cbr\u003eO2 sensors are constantly exposed to exhaust gas exceeding 600°C and accumulate combustion byproducts, operating in a very harsh environment.\n\u003cbr\u003eUsing a deteriorated or damaged O2 sensor can lead to various problems.\n\u003cbr\u003eMore than 5 years or 80,000 km since new*\n\u003cbr\u003e*Varies depending on vehicle usage conditions.\n\u003cbr\u003eTotal length: 460mm\n\u003cbr\u003eTotal length refers to the length from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible Manufacturer: Mazda\n\u003cbr\u003eCompatible genuine part number: B5E1-18-861B\u003c\/p\u003e\n\n\u003cp\u003e■Image Disclaimer\n\u003cbr\u003e*Images are for illustration purposes only.
