The O2 sensor plays an important role in detecting the oxygen concentration in the exhaust gas and feeding it back to the ECU*1.\n\u003cbr\u003eThe NTK O2 sensor detects the oxygen concentration in the exhaust gas and feeds it back to the ECU so that the fuel-air mixture ratio (air-fuel ratio) becomes the ideal stoichiometric air-fuel ratio of \"λ (lambda) = 1*2\". The ECU uses the signal from the O2 sensor to thin the fuel if it is rich relative to the stoichiometric air-fuel ratio, and enrich the fuel if it is lean, thereby controlling the engine near the stoichiometric air-fuel ratio where harmful substances in the exhaust gas are most effectively purified. In this way, the NTK O2 sensor is an important component 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. Utilizing this characteristic, the zirconia type sensor detects the difference in oxygen concentration between the inside and outside of the element (atmosphere and exhaust gas) and feeds 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 than with zirconia O2 sensors. It also enables engine control outside of the stoichiometric air-fuel ratio (λ=1), such as lean-burn control. There are also early-activating 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 element and heater structure.\n\u003cbr\u003e【Necessity of Replacement】\n\u003cbr\u003eO2 sensors are constantly exposed to exhaust gas exceeding 600°C and accumulate combustion products, working 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 the vehicle's usage conditions.\n\u003cbr\u003eTotal length: 230mm\n\u003cbr\u003eThe total length is the length from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible manufacturer: Toyota\n\u003cbr\u003eCompatible genuine part number: 89465-60150\u003c\/p\u003e\n\n\u003cp\u003e■Image Notes\n\u003cbr\u003e*Images are for illustration purposes only.
