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.
