2019丰田雷凌1.8L氧传感器 89465-02450 精确适配

2019 Toyota Levin 1.8L engine: the oxygen sensor installed in the exhaust manifold or the front exhaust pipe (OEM number 89465-02450) monitors oxygen content in real time. It feeds back to the engine control unit (ECU) to precisely adjust the air-fuel ratio, ensuring combustion efficiency and emission compliance. This sensor is designed specifically for the model and provides direct replacement installation. Installation difficulty medium; suggested labor 0.5-1 hour; avoid damaging threads or wiring harness. If the engine fault light is on, fuel consumption rises noticeably, or idle is unstable, this typically indicates sensor aging.
