O2 sensors play an important role in detecting the oxygen concentration in exhaust gas and feeding it back to the ECU*1.\n\u003cbr\u003eNTK O2 sensors detect the oxygen concentration in exhaust gas and feed it back to the ECU so that the fuel-air mixture ratio (air-fuel ratio) achieves the stoichiometric air-fuel ratio of \"λ (lambda) = 1*2.\" If the fuel is rich relative to the stoichiometric air-fuel ratio based on the signal from the O2 sensor, the ECU leans the fuel. If the fuel is lean, the ECU enriches the fuel. This control is performed 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 characteristic of generating electromotive force due to differences in oxygen concentration at temperatures exceeding 300°C. This characteristic is utilized by zirconia-type sensors to detect the oxygen concentration difference between the inside and outside of the element (atmosphere and exhaust gas) and to feed back to the ECU whether the fuel is rich or lean relative to the stoichiometric air-fuel ratio.\n\u003cbr\u003eBroadband 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. Furthermore, there are early-activation broadband air-fuel ratio sensors that maintain the characteristics of conventional broadband air-fuel ratio sensors while improving heat resistance and durability, and achieving early activation (operation starts within 5 seconds after the ignition 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 gases 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\u003eAfter 5 years or 80,000 km from new.\n\u003cbr\u003e*Varies depending on vehicle usage conditions.\n\u003cbr\u003eTotal length: 250mm\n\u003cbr\u003eThe total length is measured from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible manufacturer: Toyota\n\u003cbr\u003eCompatible genuine part numbers: 89465-58020, 89465-44070\u003c\/p\u003e\n\n\u003cp\u003e■Notes on images\n\u003cbr\u003e*Images are for illustration purposes only.
