丰田皇冠后氧传感器 89465-0P020 直接替换 提升燃油效率

This rear oxygen sensor directly replaces Toyota Crown OEM number 89465-0P020; compatibility is fine and it’s ready to use. It monitors oxygen content in exhaust and sends signals to the ECU to precisely control fuel injection, ensuring engine combustion efficiency. Fits many Toyota Crown models, especially generations 12 through 14. After installation, noticeable improvement in high fuel consumption and weak acceleration, while reducing tailpipe emissions. If you notice rough idle, check engine light on, or fuel consumption suddenly rises, the rear oxygen sensor aging is likely; replace it.
