The fuel management system monitors the converter by using the readings from both the upstream pre-converter and downstream post converter oxygen sensors. The sole purpose of the downstream oxygen sensor is to monitor how efficiently the catalytic converter is operating. The computer makes these calculations by observing the fluctuating voltage of the upstream sensor and comparing it to the downstream. If the rear reading is similar to the front, this indicates that the converter is no longer "efficiently" doing its job.
The "Service Engine Soon" light is illuminated and the P code is stored. When the converter first starts showing signs of failure, it will not immediately affect the engine. When your car burns gasoline one of the normal by-products that it creates is hydrogen sulfide. The catalytic converter is necessary to convert hydrogen sulfide into sulphur dioxide which is less harmful.
You'll likely also notice that your exhaust is much darker than it should be, potentially a grey to black smoke. Just like with many other problems in your vehicle if the catalytic converter isn't working properly it's possible that it's going to set off the check engine light on your dashboard. Since the check engine light can go off for any number of reasons you'll likely have to rely on some of these other symptoms as well to know for sure if your catalytic converter is the source of the problem or if it's something else.
The best thing that you can do when you see your check engine light on your dashboard is to invest in an OBD2 scanner. These scanners, also known as on-board diagnostic tools, are what mechanics used to diagnose the warning lights that will come up on your dashboard. You just have to plug it into your vehicle, and it will give you a code that corresponds to the specific problem that caused the light to come on in the first place.
It is related to your catalytic converter, at least then you'll know without having to do a lot of trial and error. So, as you can see, there are a number of different ways that your catalytic converter is going to let you know that there's a problem with it.
When it comes to cleaning out your catalytic converter you can definitely handle this job on your own without taking it to a mechanic if you know what to do. You may have not heard of this before and it's definitely not a manufacturer-sanctioned way to fix a problem with your vehicle, but some drivers will pull out what they call the Italian tune-up to fix problems with their vehicle that can include an issue with the catalytic converter.
As it happens, many drivers stick to driving in the city at low speeds and don't actually get their car pushed hard enough to get the catalytic converter at its most efficient operating temperature.
Ideally your catalytic converter is operating between degrees Fahrenheit and 1, degrees Fahrenheit. That's degrees Celsius and degrees Celsius. Very hot to be sure, but that's what your catalytic converter is supposed to be doing. If you take it easy on your car all the time, your converter is not going to hit those temperatures and that actually can lead to premature failure because it's not able to function the way it's supposed to.
Just if the vehicle is hundred percent clogged up. In almost all other situations, you will be able to start your four-wheeler; however, will not be able to unleash its full potential.
You would not want to find yourself in a situation where you would have to call roadside assistance and pay extra bills to have your car hauled. Yes, you can definitely do that. But, we do not recommend this by any means. It will not cause any harm to your engine, however as before mentioned, you will not be able to pass the emissions test. Also, your vehicle will be a lot louder, which means a possible police pullover and a ticket for excessive voice!
The catalytic converter contains both precious metals and ceramic granules. The heat from the exhaust gases causes the metals to become active and release a chemical reaction. This reaction changes the harmful emissions into mainly carbon dioxide CO2 and water, much less toxic.
If you notice a puddle of liquid under your vehicle after having driven it lately, there is a chance that your catalytic converter is leaking and needs to be replaced. It would be wise for you to have your catalytic converter checked as soon as possible if you notice any one or more of these symptoms. You should make an appointment to take it to a mechanic specializing in exhaust systems for proper testing and replacement recommendations.
The cost of replacing a defective catalytic converter will often come close to what it would cost to replace the entire exhaust system.
