Saturn Oxygen Sensor

When was the last time you did your tune-up? When you have it, did you check your spark plugs; did you change your oil or did you replace your oil filter? All of these things should be done when doing a tune-up. But there is another thing which you might have been forgotten. Yes, you are missing an important step and that is to check your oxygen sensors.

Most people don't think about their oxygen sensors when they are having their tune-ups. But for your information, your oxygen sensor is very important to your car's performance and endurance. And not only that, oxygen sensors also helped a lot in acquiring fuel economy and lowest emission. Because of that reasons, vehicles produced after 1980 have come with an oxygen sensor – an important measurement device for the fuel control computer.

Here's how your Saturn oxygen sensor works. Oxygen sensors reads the amount of oxygen in your exhaust and tells your fuel injector how much fuel the engine needs to maintain the proper air-fuel ratio because all spark combustion engines need the proper air-fuel ratio to operate properly. The oxygen sensor is mounted in the exhaust manifold downpipe facing the catalytic converter or between the exhaust manifold and the catalytic converter.

The sensing element on almost all oxygen sensors in use is a zirconium ceramic bulb coated on both sides with a thin layer of platinum. The exterior of the bulb is exposed to the hot exhaust gases, whereas the interior of the bulb is vented internally through the sensor body or wiring to the outside atmosphere.

It is very important to ensure that your Saturn oxygen sensor is always in good working condition because when it fails, the computer could no longer sense the air/fuel ratio thus ends up guessing. Your car will start to perform badly and worst is it will use more fuel than it needs to.
