丰田汉兰达氧传感器89465-48250，通用替换89465-48110原厂标准安装

Toyota Highlander oxygen sensor (OEM 89465-48250) compatible with replacing 89465-48110; standard installation requires no wiring changes. Monitors exhaust oxygen content and feeds back to the ECU to adjust air–fuel ratio for combustion efficiency. Fits Highlander 2.7L and 3.5L; after installation, it can resolve high fuel consumption, weak acceleration, or excessive emissions. If the engine warning light is on constantly, idle is unstable, or the exhaust emits black smoke, it’s generally due to aging oxygen sensor; replace promptly.
