丰田皇冠氧传感器89465-0P010，通用级替换0P020/50170即插即用

When your Toyota Crown shows rough idle, noticeably increased fuel consumption, stronger exhaust odor, or engine fault light is on, it usually indicates aging or failed oxygen sensors that cannot accurately monitor exhaust oxygen content. When functioning properly, the sensor feeds the ECU with air-fuel ratio signals to help maintain optimal combustion efficiency, ensuring smooth power and fuel economy. This is a universal replacement, compatible with OEM numbers 89465-0P010, 0P020 and 50170, for many Toyota Crown models with plug-and-play installation. Ensure sensor threads are clean and tightened to the specified torque to avoid thread damage from over-tightening or leaks from looseness.
