The Lexus IS300 Oxygen Sensor is one of the car's major parts that go to an extent in proving the automobile giant's reliability and performance. Present in different IS300 models, it is one of the major devices that control the air/fuel ratio and contributes to the smooth running of the vehicle's engine while reducing emission. To demonstrate a principle of operation of the Lexus IS300 Oxygen Sensor, the engine emits unburned oxygen in its exhaust and converts this into a voltage signal so that the engine control computer can then manipulate the fuel injector pulse width to ensure that the car's engine runs efficiently in a "closed loop" state. Normally, the IS300 has two oxygen sensors one before the catalytic converter and the other after the converter, but the before sensor is most essential for giving feedback signals. This also improves on the fuel economy as well as safety of the vehicle since it provides for proper working of the catalytic converter. A newer model of Lexus IS300 Oxygen Sensor has been developed with the usage of zirconium dioxide, a newer compound than the platinum type, and the inclusion of air/fuel ratio sensors giving it a wider range of measurement. The Lexus IS300 Oxygen Sensor requires regular maintenance because contaminants and age may impact its function and result in the vehicle emitting more during its operation, and will function at a lower level. This product of the reputed Lexus is indeed a unique name in the global automotive market specializing in oxygen sensors, adding strength to the brand's legacy carrying the promise of luxurious cars.
