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 optimal stoichiometric air-fuel ratio \"λ (lambda) = 1*2.\" If the fuel is rich compared to the stoichiometric air-fuel ratio according to the signal from the O2 sensor, the ECU thins the fuel. If it is lean, the ECU enriches the fuel, thereby controlling the engine near the stoichiometric air-fuel ratio, which most effectively purifies harmful substances in the exhaust gas. Thus, the NTK O2 sensor is an important component in 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 are characterized by detecting the difference in oxygen concentration between the inside and outside of the element (atmosphere and exhaust gas) and feeding back to the ECU whether the fuel is rich or lean relative to the stoichiometric air-fuel ratio.\n\u003cbr\u003eFull-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 other than the stoichiometric air-fuel ratio (λ=1), such as lean-burn control. Additionally, there are early-activation full-range air-fuel ratio sensors that maintain the characteristics of conventional full-range air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (starts operating within 5 seconds of the engine key being turned ON) due to the 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 have combustion products adhering to them, working in very harsh environments.\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.\n\u003cbr\u003eTotal length: 750mm\n\u003cbr\u003eTotal length is the length from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible manufacturer: Toyota\n\u003cbr\u003eCompatible genuine part number: 89465-30640\u003c\/p\u003e\n\n\u003cp\u003e■Notes on images\n\u003cbr\u003e*Images are for illustration purposes only.
