9 Symptoms of a Clogged Catalytic Converter

What are some of the symptoms of a clogged catalytic converter which you should be aware of? The catalytic converter is one of the components of the exhaust system. It neutralizes the harmful gases from the combustion chamber before expelling them through the exhaust pipe. Catalytic converters are prone to failure, and it is costly to replace them. Knowing the signs, your truck will show when the catalytic converter is faulty is necessary.

Symptoms of a Clogged Catalytic Converter

Here are some of the top symptoms of a clogged catalytic converter in a truck that you need to keep an eye on.

Check Engine Light

The appearance of this light on your dashboard is an indication that there is a problem with your truck. If the scanning of this check light reveals the error code related to the catalytic converter, use the user guide to decode the error code.

Acceleration Lag

Delays or reduced power when you press the acceleration pedal indicate that your catalytic converter is faulty. To determine if your catalytic converter is clogged, ask someone to press the acceleration pedal as you keep your hands on the exhaust system. If there is a larger amount of exhaust fume from the truck, your acceleration might be bad.

Irregular Fuel Consumption

Increased or decreased fuel consumption is a symptom of a bad catalytic converter. Low fuel consumption can ruin your engine, which might be very costly to repair.

A clogged exhaust system leads to improper combustion, and your engine will work extremely hard to produce the required energy. A clogged catalytic converter can lead to higher fuel consumption.

Bad Smell

Your truck will smell sulfur when the catalytic converter is damaged. The airflow into the combustion chamber will be restricted, giving your engine too much fuel. You will feel a bad smell in your truck when there is too much fuel in the combustion chamber.

Discolored Housing

When the housing of your catalytic converter turns blue or any other color is an indication that your catalytic converter is faulty.

Problems with Starting

When your catalytic converter is blocked, the engine will receive too much fuel, which it will not be able to burn. Back pressure will be generated, making it hard for the engine to eliminate the exhaust gases.

Increased Emissions

Your catalytic converter will not be efficient when it is clogged. Your truck will emit more harmful gases into the atmosphere. The catalytic converter’s role is to regulate and eliminate harmful emissions.

Misfiring Engine

Oxygen flow into the combustion chamber gets restricted when the catalytic converter is clogged, which will reduce the airflow into the combustion chamber leading to an increase in temperature due to the accumulation of unburnt gases, which will make your engine misfire.

Rattle and Other Noises

You will experience weird noises when your catalytic converter is clogged. A honeycomb inside the catalytic converter wears out and breaks into pieces. When the honeycomb is broken, you will experience a rattling noise from your catalytic converter as you rave your engine.

Conclusion

The catalytic is one of the parts of the exhaust system which can interfere with the entire engine when clogged. Knowing some of the signs of a clogged catalytic converter is necessary so that you can repair it earlier before it escalates into other issues that will need more cash to fix. 

Failing Catalytic Converter

Symptoms of a Bad or Failing Catalytic Converter

The catalytic converter is an integral part of the exhaust system, which helps neutralize dangerous gases emitted from the combustion chamber. The catalytic converter is made to serve your truck throughout its lifetime, but it can break down or wear, which will compel you to repair it. How will you know that you have a failing catalytic converter? Here is more into finding out more on that.

When your catalytic converter is faulty, the exhaust gases emitted from your truck will pollute the environment, fuel consumption will not be economical, and other exhaust components will get damaged. 

Symptoms of a Failing Catalytic Converter

Several chemical reactions occur in the catalytic converter to neutralize the harmful gases from your truck’s combustion chamber. Here are some symptoms you will experience when your catalytic converter is faulty.

Your Engine Will Misfire

Engine misfires are some early signals that your catalytic converter is faulty. When your engine misfires, your catalytic converter is overheating. It indicates that the combustion is not complete in the combustion chamber.  

When the converter is clogged, it will overheat, and too much heat will destroy the converter. 

The smell of a Rotten Coming From Your Exhaust Pipe.

When your catalytic converter is damaged, you will feel a bad smell similar to that of a rotten egg. The converter will not be able to neutralize the harmful gases. Therefore, they will be emitted to the surrounding. The sulfur compound is one of the fuel combustion products. If your catalytic converter is not functioning, sulfur will be responsible for producing a bad smell. 

When the Engine Check Light Appears

Trucks have an internal computer that relays on the sensor to show various check lights on the dashboard. When your catalytic converter is bad, the ratio of fuel to air in the combustion chamber will be affected, and your truck will emit toxic gases to the surrounding.

If your converter is not working properly, the engine check light will appear on your dashboard. The engine check light also may signal other engine problems. It would help if you took your truck for a checkup when the check light appeared.

Starting Problems

You will experience difficulties starting your truck when your exhaust system is clogged. A clogged catalytic converter will not neutralize the harmful gases from your combustion chamber. The toxic gases will be in the combustion chamber, leading to pressure build-up. The accumulation of exhaust gases can lead to an engine stall or starting problems.

Increased Fuel Consumption

When the catalytic converter is clogged, the airflow into the combustion will reduce, and the engine will burn more fuel than normal. When the exhaust flow is limited, your acceleration will be affected, and you will press acceleration frequently. More acceleration introduces more fuel to the combustion chamber, leading to flooding. 

A bad catalytic converter reduces the amount of oxygen flow into the combustion chamber, making the engine work harder to produce the energy required. 

Conclusion

A faulty catalytic converter interferes with the normal operation of the engine. When you experience any of the above signs, conclude that your catalytic converter is faulty. Take your truck for a thorough mechanical checkup to fix it.
