Increasing emissions is one of the bad catalytic converter symptoms you should notice. Excessive heat under the vehicle.

The catalytic converter is part of the exhaust system processing all exhaust leaving the engine before it can escape into the atmosphere.

What happens when a catalytic converter goes bad. This will be especially noticeable at times when you re maintaining a consistent speed. Unburnt fuel left in the exhaust by the bad catalytic converter produces the odor and may even cause dark exhaust smoke. When failing you may notice a sulfuric rotten egg like smell coming from the exhaust.

So a high level of carbon emission is the obvious consequence of a bad exhaust system. Again because a bad torque converter means that your flow of transmission fluid isn t what it s supposed to be you can also have issues will transmission surges or lags while you drive. A bad or clogged catalytic converter can ultimately lead to engine failure so it s important to address the issue promptly.

The metals in the catalytic converter react with the unburned fuel and oxygen causing a catalytic reaction that produces heat. Among the symptoms of a bad catalytic converter are. The smell of sulfur or rotten eggs from the exhaust.

Catalytic converter failure can be a pain to fix. This part is placed between the engine and the exhaust muffler on the underside of the car. If you have a car that features the continual oil change burns oil or leaks coolant into the engine these issues can lead to a clog as it will coat the internals of the catalytic converter blocking its ability to expel the gas through the honeycombs.

A bad or failing catalytic converter can also cause an illuminated check engine light. And yes it s the heat that does the job. Check engine light comes on.

A bad converter can cause some changes in exhaust gases but these changes can also come from another issue that could damage the converter. A catalytic converter is a vital part of the vehicle s exhaust system that works to convert harm ful gases into safe compounds that can be emitted into the atmosphere and cause less damage to the environment. This essential emissions system component can sap miles per gallon and drive up your fuel consumption as it gradually loses efficiency and impacts your engine s power production.

White smoke coming out of the tailpipe of a vehicle typically indicates that the engine is overheating. When a converter is failing it can t do its job properly which is to reduce gaseous emission.
