Rattling Catalytic Converter
This is a great example of a noise a catalytic converter may make if it comes apart internally. This is a somewhat common way in which a catalytic converter can fail. However, a catalytic converter dose not have to make noise to be bad. This is just one example and one symptom of a bad catalytic converter.
Note: While this is a somewhat common symptom of a catalytic converter that has come apart inside it is not common for a converter to come apart on its own. There is usually a root cause to why the converter came apart. Usually an ignition misfire is to blame. When an ignition misfire occurs the unburned fuel enters the cat converter and overwhelms it. The catalyst temperature rises above normal operating temperature and causes the catalyst to meld down. There are other things that can cause a catalytic converter to melt down also such as a leaking fuel injector, a faulty O2 sensor, a faulty MAP sensor, and the list goes on. Proper diagnosis and repair of root causes of catalytic converter failure must be address before replacing a catalytic converter or repeat failure could occur.
