丰田氧传感器 89465-53060 / 89465-53080，直接替换原厂部件

Toyota Camry, Corolla, RAV4 and other models compatible oxygen sensor (OEM number 89465, corresponding to 89465-53060/89465-53080) directly replaces the original part with no modification. It monitors exhaust oxygen content and feeds back to ECU to adjust air-fuel ratio, ensuring combustion efficiency. If check engine light is on, idle is unstable, or exhaust emits black smoke, sensor aging is indicated and replacement is needed. This part can reduce fuel consumption and improve acceleration.
