丰田花冠后氧传感器89465-12700，通用标准延长发动机寿命

Toyota Corolla rear oxygen sensor (OEM number: 89465-12700) is built strictly to original standards, with stainless steel housing and high-temperature ceramic elements; welded joints are reinforced to withstand typical exhaust temperature fluctuations and vibrations. Suitable for Toyota Corolla (2000–2007) and same-platform Auris (E120/E130 series). This sensor continuously monitors exhaust oxygen content, feeds back to the ECU to precisely adjust air-fuel ratio, thereby optimizing combustion efficiency, reducing fuel consumption, and extending engine life.
