丰田04款氧传感器89465-68070

If the vehicle shows rough idle, noticeably higher fuel consumption, excessive emissions, or the engine warning light is on, this usually indicates an aging NOx sensor. The sensor in normal operation provides real-time NOx feedback to the ECU to help regulate fuel injection and ensure combustion efficiency and emissions compliance. OEM number 89465-68070, compatible with 33160/28290, fits Toyota 04-series models (such as Camry, Corolla, etc., 2.0L/2.4L). Install only when the engine is cold to avoid scalding; clean the threads before removing the old sensor, apply anti-seize compound when installing the new part, and tighten to the specified torque to prevent leaks or damage.
