Is your car’s check engine light on and your mechanic is telling you it’s because of a clogged catalytic converter? Don’t panic – it may just need a little TLC in the form of a catalytic converter cleaner. But what exactly is catalytic converter cleaner, and what are the signs it’s needed?
Catalytic converter cleaner is a liquid additive that is added to the fuel tank. It helps dissolve and clean deposits from a car’s catalytic converter and oxygen sensors, and restore lost engine performance and improve emissions. It is often used to fix a PO420 or PO430 check engine light trouble code.
The simple truth is, catalytic converters are essential for controlling vehicle emissions. They play a crucial role in keeping our air clean and preventing unpleasant odors from exiting the exhaust pipes.
And, if you are suddenly seeing a check engine light related to a PO420 or PO430 error code, it means that the oxygen sensors (O2 sensors) are showing low efficiency from the catalytic converter.
Simply put, this means that the catalytic converter is not doing what we’d expect from it – reducing emissions.
But don’t worry, you don’t have to shell out for an expensive new catalytic converter. All it needs is a good cleaning.
In this guide, we will explore the signs that indicate the need for catalytic converter cleaning, the benefits of using catalytic converter cleaners, and address frequently asked questions.
Then to wrap it all up, we will provide recommendations on where to purchase these cleaners.
Let’s jump into this!
What Are The Signs that Indicate the Need for Catalytic Converter Cleaner?
Perhaps the most common sign that your catalytic converter needs a good cleaning is a loss of engine power. This can often be pretty evident when driving up steep hills or trying to merge onto the highway. The car might just feel a bit sluggish.
And then of course, is the check engine light. If you are getting a PO420 or PO430 error code, it means the catalytic converter and O2 sensors are dirty.
Because of a build up of carbon on the catalytic converter, it means the catalyst on the catalytic converter is not able to reduce the amount of emissions that you’re car is putting out.
Truth is, catalytic converters can become clogged or inefficient over time due to the accumulation of carbon deposits and oil residues. Simply put, if your vehicle accumulates a high number of miles each year or if it consumes oil, expect a high likelihood of a dirty converter.
And don’t neglecting these signs, as it can lead to more severe damage to your vehicle’s exhaust system and engine.
Promptly addressing these symptoms can help prevent further complications later down the road. Not to mention save on fuel expenses and help keep our air clean too.
What Causes Catalytic Converters and O2 Sensors to Get Dirty?
So, why do catalytic converters and O2 sensors get all gunked up? Well, there are a few reasons. First off, if your engine isn’t burning fuel efficiently, you can end up sending carbon deposits down into the catalysis.
Another culprit is leaks. If your engine is consuming oil or coolant, those sneaky liquids can contaminate your the catalytic converter and O2 sensors. And prolonged exposure to oil or coolant will surely containment the converter and O2 sensors, leading to reduced power or check engine light.
Remember, these parts can also get dirty simply with age and usage too. With age and miles, even the best things in life need a little TLC.
So, if you notice your vehicle isn’t performing as it should, or your check engine light is on and glowing – it’s time to give those converters and sensors some love.
