丰田氧传感器 89465-60330 稳定信号 持久耐用 原厂替代件

When your Toyota experiences idle instability, noticeably higher fuel consumption, weak acceleration or engine warning light, oxygen sensor aging or failure is likely. This sensor monitors exhaust oxygen content and provides feedback to ECU to precisely control air–fuel ratio for efficient burning and lower emissions. This is an OEM replacement, OEM 89465-60330; fits many Toyota models (e.g., Camry, Corolla, RAV4). Installation: use a dedicated socket to avoid thread damage; operate with cold engine to prevent burns.
