丰田后氧传感器 89465-30430 即插即用无需编程 替换原厂

When your Toyota vehicle shows check engine light, abnormal fuel consumption, or failed exhaust emissions tests, the rear oxygen sensor may have aged or failed, causing inability to accurately monitor oxygen levels after the catalytic converter. The sensor normally feeds back to the ECU to adjust the air-fuel ratio for efficient combustion and reduced emissions. This rear oxygen sensor OEM number is 89465-30430; compatible with Toyota Camry, Corolla, RAV4 and many others; no programming required, plug-and-play. During installation ensure sensor threads are clean and apply a suitable anti-seize compound to prevent seizing at high temperatures.
