丰田埃尔法GSR50 左前氧传感器 89467-58010

When your Toyota Alphard GSR50 shows engine fault indicator light on, idle instability, weak acceleration, or noticeably increased fuel consumption, this usually indicates that the left front upstream oxygen sensor has aged or failed and cannot accurately monitor oxygen content in the exhaust. When functioning properly, this sensor provides real-time feedback of the air-fuel ratio to the ECU to help the engine maintain optimum combustion efficiency, thereby reducing emissions and improving power response. This product OEM number is 89467-58010, compatible with Toyota Alphard GSR50. Installation must be performed with the engine cool to avoid burns; prior to removing the old sensor, use a dedicated socket, and avoid damaging threads or wiring interfaces.
