Thus, NTK O2 sensors are an important component in reducing harmful substances in exhaust gases. \u003c\/p\u003e\n\n\u003cp\u003eSpecifications\n\u003cbr\u003e【Features and Structure】\n\u003cbr\u003eZirconia elements have the characteristic of generating electromotive force due to differences in oxygen concentration at temperatures exceeding 300°C. Utilizing this characteristic, 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 mixture is rich or lean compared 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 than with zirconia O2 sensors. It also enables engine control at air-fuel ratios other than the stoichiometric air-fuel ratio (λ=1), such as lean burn control. Additionally, there are early-activation type wide-range air-fuel ratio sensors that maintain the characteristics of conventional wide-range air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (starts operating within 5 seconds after the engine key is turned ON) through an integrated structure of the element and heater.\n\u003cbr\u003e【Need for Replacement】\n\u003cbr\u003eO2 sensors are constantly exposed to exhaust gases 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 from new*\n\u003cbr\u003e*Varies depending on vehicle usage conditions.\n\u003cbr\u003eOverall length: 1210mm\n\u003cbr\u003eThe overall length is the length from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible manufacturer: Nissan\n\u003cbr\u003eCompatible genuine part number: 226A1-VG301\u003c\/p\u003e\n\n\u003cp\u003e■Image Notes\n\u003cbr\u003e*Images are for illustration purposes only.
