Catalytic converters were
introduced in 1975 and have been mandatory on all vehicles manufactured since
An internal combustion engine, like the kind in your vehicle, creates emissions
that are bad for the environment. To reduce pollution, a catalytic converter
changes harmful gases into harmless ones. So you can see why it’s so
important—to everyone—that your catalytic converter is working properly.
The catalytic converter is located in your exhaust system, between the exhaust
manifold and the muffler. Harmful gases, like carbon monoxide, hydrocarbons and
oxides of nitrogen enter the converter. There they react with chemicals and are
converted into less harmful emissions like water, nitrogen and carbon dioxide.
Normally if there’s a problem, the “Check Engine” or “Service Engine Soon” light
will appear on your dashboard. . We’ll check the diagnostic codes, and if
there’s trouble with your converter or O2 sensor, he’ll take care of it.
(Remember, that dashboard light doesn’t mean you have to stop driving
immediately. It’s meant as an alert, but you should see your mechanic.
Most times, a malfunctioning catalytic converter is a sign of another problem,
like misfiring spark plugs.
