O2 sensors play a crucial role in detecting the oxygen concentration in exhaust gases and feeding this information 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 air-fuel mixture ratio (air-fuel ratio) becomes the optimal stoichiometric air-fuel ratio \"λ (lambda) = 1*2\". If the ECU receives a signal from the O2 sensor indicating that the fuel is rich relative to the stoichiometric air-fuel ratio, it thins the fuel; if it's lean, it enriches the fuel. This control ensures operation near the stoichiometric air-fuel ratio, which most effectively purifies harmful substances in the exhaust gas. Thus, NTK O2 sensors are important components for reducing harmful substances in exhaust gases. \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 oxygen concentration difference 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\u003eWideband 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 compared to zirconia O2 sensors. It also allows for 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 wideband air-fuel ratio sensors that maintain the characteristics of conventional wideband air-fuel ratio sensors while improving heat resistance and durability, and achieve early activation (start operation within 5 seconds after the ignition key is turned ON) through an integrated element and heater structure.\n\u003cbr\u003e【Need for Replacement】\n\u003cbr\u003eO2 sensors are constantly exposed to exhaust gases exceeding 600°C and accumulate combustion byproducts, 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\u003eOverall length: 210mm\n\u003cbr\u003eThe total length is the length from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible manufacturer: Daihatsu\n\u003cbr\u003eCompatible genuine part number: 89465-B5042\u003c\/p\u003e\n\n\u003cp\u003e■ Image Notes\n\u003cbr\u003e*Images are for illustration purposes only.
