IS300 O2 Sensor

The engine doesn’t just need to have carbon, fuel and hydrogen components for the combustion process. These elements need to be of perfect balance to ensure less toxic emissions. There’s actually no specific ratio required for all types of engines. For gasoline-powered Lexus IS300 engine, 14:7:1 is the ideal ratio. In order to reach that ratio, Lexus IS300 oxygen sensor is integrated.

Oxygen sensor is a hollow tube possessing three compartments divided by a U-shaped platinum-coated rod. That platinum coating is the material that produces a chemical reaction leading to voltage generation. The current produced is the one that’s used to check the mixture hundreds of times per minute in order to obtain accurate data and determine whether the red-hot exhaust is lean or rich. After the data is obtained, it would then be sent to a computer to do necessary adjustments and reach a more balanced ratio.

However, if your Lexus IS300 oxygen sensor is already defective, where the sensitivity to oxygen component and insensitivity to other properties has gone inefficient, the result will be stinky rotten egg smell and black smoke emerging from the exhaust pipe. Aside from becoming unfriendly to the environment, your vehicle will also suffer from poor mileage and low engine performance.

Oxygen sensors normally require replacement after running 100,000 miles. If your Lexus IS300 has already run more than that, its oxygen sensor now badly needs replacement. our company has the best line of high quality Lexus IS300 oxygen sensor to replace your old or defective oxygen sensors.
