What is the impact of catalytic converter failure?

The impact of catalytic converter failure primarily leads to increased harmful emissions and potential engine damage. Catalytic converters are vital components in a vehicle's exhaust system designed to reduce harmful pollutants released into the atmosphere. When functioning correctly, they convert toxic gases like carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances.

If the catalytic converter fails, these harmful gases are not properly converted and are instead emitted into the environment, contributing to air pollution. Additionally, a failing catalytic converter can cause back pressure in the exhaust system, potentially leading to engine performance issues and damage over time. Therefore, the failure of this component has serious implications for both environmental health and the vehicle's internal systems.
