What Happens When a Catalytic Converter Goes Bad?

Your vehicles catalytic converter serves an important role: it transforms chemicals created during the combustion process from hazardous to harmless, thus reducing air pollution. It achieves this remarkable feat thanks to a honeycomb mesh that is coated with a catalyst. Through a chemical reaction, this catalysts converts the chemical makeup of the emissions. While catalytic converters are designed to last for the lifetime of a vehicle that doesnt always happen.

To the average driver, lower fuel efficiency is one of the most noticeable symptoms of a bad catalytic converter.

Can you drive a car with a bad catalytic converter?

A bad catalytic converter will give off higher emissions than allowed by the state. So a car with a malfunctioning catalytic converter will not pass a vehicle inspection. And that means you won’t be able to drive your vehicle legally.

How can you tell when the catalytic converter is bad?

Sluggish engine performance..Reduced acceleration..Dark exhaust smoke..The smell of sulfur or rotten eggs from the exhaust..Excessive heat under the vehicle.

What happens if I don't replace my catalytic converter?

Because a failing catalytic converter can no longer properly convert the toxic fumes that flow through it into less harmful materials, one of the side effects that you are going to experience is the smell produced by the gases flowing through it. In particular the exhaust is going to have a sulphur type smell.

Diagnosing a bad catalytic converter is not the simplest job in your vehicle, but is a key part of keeping your engine healthy and enhancing the longevity of your car. There are certain steps you can take to diagnosing your catalytic converter and fixing the root cause of the problems before the bad catalytic converter ruins your engine.

While durable and tough to withstand most conditions, the catalytic converter can slowly fail throughout use as the catalyst elements wear down and become damaged. However, if the catalytic converter has undergone intense internal damage, the replacement will mean the mechanism is not working properly and the odor can be smelled by the driver and passengers.

Catalytic converters are usually used in tandem with the internal combustion engines that are given power by either gasoline or diesel, depending on the specific make, model, and year of the car. These catalysts burn the carbon monoxide and hydrocarbons that are still located in the incoming gas, helping to get rid of the smog produced by the unburnt fuel. This sensor relays information back to the electronic control unit about how much oxygen is within the exhaust gases, with the on-board computer adjusting the air and fuel mixture accordingly.

This is key to the longevity and the lifespan of your car and the overall inner workings of your vehicle, by neutralizing hazardous compounds in your exhaust system, like carbon monoxide. This is due to the fact that your catalytic converter could become clogged over time, filled with debris and rust, and exhaust will become trapped in your cars engine. If your catalytic converter is damaged or failing, this rattling will be very loud when the car starts or will get worse as you continue driving your vehicle.

If you are hearing a rattling noise with the other symptoms on this list, like decreased performance and gas mileage, there is a good likelihood that your catalytic converter is what is at fault.

The liver is a vital part of human anatomy. Its main job is to detoxify chemicals and metabolize drugs in blood coming from the digestive tract to ensure it’s clean and healthy before it travels to the rest of your body. Livers are designed to last a lifetime, but they can fail if clogged up with unhealthy fat.

Problems that may make you fail the test include an increased level of carbon emissions, contaminated antifreeze or motor oil or any of the other symptoms mentioned above. Finally, if your vehicle doesn’t accelerate properly when you step your foot on the gas pedal, it could be another sign your catalytic converter is clogged.

Reduced engine performance or efficiency is a red flag, as it’s another sign that exhaust is trapped in front of the catalytic converter. The good news is that just like you can treat liver failure if you catch it early enough, you can potentially clean out a clogged catalytic converter if you address it before it damages your other car components.

Whats that wretched smell? Have you ever finished driving your vehicle and noticed the acrid scent of rotten eggs? If so, pay attention, this is often the first and most common sign that your catalytic converter is starting to fail.

Symptoms of a Bad Catalytic Converter

Your vehicle’s catalytic converter serves an important role: it transforms chemicals created during the combustion process from hazardous to harmless, thus reducing air pollution. It achieves this remarkable feat thanks to a honeycomb mesh that is coated with a catalyst. Through a chemical reaction, this catalysts converts the chemical makeup of the emissions. While catalytic converters are designed to last for the lifetime of a vehicle that doesn’t always happen.Over time, residue from the exhaust gases a cat is rendering harmless build up within its honeycomb-shaped interior. Sometimes, so much residue builds up that the catalytic converter clogs and stops working. If this integral part fails, your vehicle will spew hazardous emissions into the environment and you may not even know it — until your vehicle fails its next inspection.
