兰德酷路泽URJ201前氧传感器 89467-60030 发动机空燃比控制

Toyota Land Cruiser URJ201 upstream oxygen sensor, OEM part number 89467-60030, directly replaces the factory part without additional modification. This sensor is mounted at the front of the exhaust system to monitor the air–fuel ratio and feed back to the ECU to precisely control fuel injection, ensuring combustion efficiency. After installation, it effectively resolves high fuel consumption, weak power, acceleration hiccups, and persistent engine warning light issues. If idle is unstable, there is a strong exhaust odor, or cold-start is difficult, timely replacement of this sensor is recommended.
