The ECU controls the fuel to be leaner when the fuel is rich relative to the stoichiometric air-fuel ratio based on the signal from the O2 sensor, and richer when it is lean, thereby controlling it near the stoichiometric air-fuel ratio that most effectively purifies harmful substances in the exhaust gas. In this way, 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\/Structure】\n\u003cbr\u003eZirconia elements have the characteristic of generating electromotive force due to differences in oxygen concentration at temperatures exceeding 300°C. Using 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\u003eFull-range air-fuel ratio sensors can detect how rich or lean the mixture is relative to the stoichiometric air-fuel ratio. This allows for more precise engine control than 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. In addition, 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 (start operating 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\u003eMore than 5 years or 80,000 km since new*\n\u003cbr\u003e*Varies depending on vehicle usage conditions.\n\u003cbr\u003eTotal length: 330mm\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: 89465-26140\u003c\/p\u003e\n\n\u003cp\u003e■Notes on images\n\u003cbr\u003e*Images are for illustration purposes only.
