What are the Symptoms of a Bad Catalytic Converter?

A catalytic converter reduces harmful emissions from a vehicle's exhaust to less toxic substances. It is a crucial component of a car's exhaust system and is located between the engine and the muffler. Like most other components, a catalytic converter will get damaged, broken, clogged, and malfunctioned. Usually, a faulty catalytic converter will alert you with these 5 signs before it completely fails.

The Check Engine Light Illuminates

Your vehicle's internal computer uses the check light engine to signify internal car problems. When the computer detects that the catalytic converter is not catalyzing the gases as it should, it will set off the engine light to notify the driver of an impending problem. Please note that other internal car problems can also cause the engine light to illuminate. That is why it is important that you leave your vehicle's diagnosis and repair to professional technicians.

Degraded Engine Performance

Here is one of the most common indicators of a faulty catalytic converter. A failing catalytic converter creates back pressure that prevents the engine from functioning and running freely. Besides, the impulsive bursts of pressure can make your car shake and even stall the engine while driving.

Your Vehicle Will Fail the Emission Test

As aforementioned, the catalytic converter's main function is to facilitate the release of less toxic emissions from your car. Without a doubt, if your car's catalytic converter is failing, it will definitely fail the emission test. In most American states, the test is done once per year, and only cars with functional catalytic converters are legally allowed on the road.

Rattling Noises

If you hear unusual noises emanating from under your vehicle, it might be a sign of a bad catalytic converter. While a failing catalytic converter will not necessarily cause the vehicle to rattle, it can damage the honeycomb mesh causing the noise.

A properly working catalytic converter means high performance, great fuel economy, and incredible acceleration, to mention a few. Of course, you can still use your vehicle even with a faulty catalytic converter. However, overlooking the problem can translate to worse damage and expensive repair costs.
