If the ECU receives a signal from the O2 sensor indicating that the fuel is rich compared to the stoichiometric air-fuel ratio, it leans the fuel. If the fuel is lean, it enriches the fuel. This controls the engine near the stoichiometric air-fuel ratio where harmful substances in the exhaust gas are most effectively purified. Thus, NTK O2 sensors are an important component in reducing harmful substances in exhaust gas.\n\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 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 fuel 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 outside of the stoichiometric air-fuel ratio (λ=1), such as lean burn control. Furthermore, some early activation type wide-range air-fuel ratio sensors maintain the characteristics of conventional wide-range air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (start operation within 5 seconds after the engine key is turned on) through an integrated structure of the element and heater.\n\u003cbr\u003e【Necessity of Replacement】\n\u003cbr\u003eO2 sensors are constantly exposed to exhaust gas exceeding 600°C and accumulate combustion products, operating in a very harsh environment.\n\u003cbr\u003eUsing a deteriorated or damaged O2 sensor can lead to various problems.\n\u003cbr\u003e5 years or 80,000 km or more from a new car*\n\u003cbr\u003e*Varies depending on vehicle usage.\n\u003cbr\u003eTotal length: 550mm\n\u003cbr\u003eThe total length is from the gasket to the tip of the connector.\n\u003cbr\u003eHeat shields and other parts are included; please use them as is without removing them.\n\u003cbr\u003eCompatible Manufacturer: Subaru\n\u003cbr\u003eCompatible Genuine Part Number: 22690-AA891\n\u003c\/p\u003e\n\n\u003cp\u003e■Notes on images\n\u003cbr\u003e*Images are for illustration purposes only.
