Is It Serious If the Catalytic Converter Is Broken?

[LilahLee]

The catalytic converter being broken is serious. The impacts of a damaged catalytic converter include: 1. Increased exhaust pollution: Without the catalytic converter's ability to catalyze and reduce harmful gases in the exhaust emissions, vehicle pollution will worsen. 2. Engine warning light on: When the engine's electronic control unit (ECU) cannot detect or detects abnormal signals from the oxygen sensor, the engine warning light will illuminate. 3. Increased fuel consumption and reduced power: A damaged catalytic converter will affect the normal signal of the oxygen sensor, leading to the engine's inability to precisely control the fuel injection amount, resulting in increased fuel consumption and reduced power. 4. Carbon buildup, increasing the engine's 'chronic diseases': As the air-fuel ratio of the combustible mixture in the cylinder becomes severely imbalanced, incomplete combustion will produce large amounts of carbon deposits accumulating in the cylinder, thereby increasing the engine's 'chronic diseases.'
