Symptoms of a Faulty Catalytic Converter?

[VanAva]

Symptoms of a faulty catalytic converter are as follows: 1. Poor exhaust flow and engine overheating. If the catalytic converter is damaged due to clogging, the accumulation of high-temperature exhaust gases can easily cause the engine temperature to rise excessively. 2. The engine warning light comes 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. Carbon buildup. As the air-fuel ratio of the combustible mixture in the cylinder becomes severely imbalanced, incomplete combustion leads to significant carbon buildup inside the cylinder, increasing the engine's 'chronic' issues. 4. Increased fuel consumption and reduced power. A damaged catalytic converter will affect the normal signals from the oxygen sensor, causing the engine to inaccurately control the fuel injection volume. 5. Increased tailpipe pollution. Without the catalytic converter to catalyze and reduce harmful emissions, the vehicle's tailpipe pollution will worsen.
