What Impact Does a Faulty Catalytic Converter Have on a Vehicle?

[Valentina]

A faulty catalytic converter can have the following impacts on a vehicle: 1. Increased exhaust pollution: Without the catalytic converter to reduce harmful emissions, the vehicle's exhaust pollution will worsen; 2. Engine warning light activation: When the engine's electronic control unit (ECU) cannot detect or receives abnormal signals from the oxygen sensor, the engine warning light will illuminate; 3. Increased fuel consumption and reduced power: A damaged catalytic converter can affect the oxygen sensor's signals, leading to inaccurate fuel injection control, resulting in higher fuel consumption and decreased power; 4. Carbon buildup: As the air-fuel ratio in the cylinders becomes severely imbalanced, incomplete combustion will cause excessive carbon deposits to accumulate in the cylinders, exacerbating chronic engine issues.
