The ECU controls the engine near the stoichiometric air-fuel ratio, which most effectively purifies harmful substances in exhaust gas, by thinning the fuel when the fuel is rich relative to the stoichiometric air-fuel ratio based on the signal from the O2 sensor, and enriching the fuel when it is lean. In this way, NTK O2 sensors are important 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. Utilizing 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\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 other than the stoichiometric air-fuel ratio (λ=1), such as lean burn control. In addition, there are early activation type 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 (start operation 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 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 from a new car*\n\u003cbr\u003e*Varies depending on vehicle usage.\n\u003cbr\u003eTotal length: 385mm\n\u003cbr\u003eTotal length is the length from the gasket to the tip of the connector.\n\u003cbr\u003eCompatible manufacturer: Honda\n\u003cbr\u003eCompatible genuine part number: 36532-PSA-J01\u003c\/p\u003e\n\n\u003cp\u003e■Notes on Images\n\u003cbr\u003e*Images are for illustration purposes only.
