Does Damage to the Three-Way Catalytic Converter Affect the Vehicle?

[StValeria]

Damage to the three-way catalytic converter has significant impacts on the vehicle. It affects fuel consumption, exhaust emissions, and more. Below are detailed explanations: Excessive Exhaust Emissions: If the three-way catalytic converter is clogged or fails, it will prevent the vehicle's exhaust from being properly purified. Harmful gases such as CO, HC, and NOx will be directly emitted, leading to non-compliant exhaust emissions and making the vehicle fail the annual inspection. Increased Fuel Consumption: A clogged three-way catalytic converter can disrupt the normal operation of the oxygen sensor, affecting the accuracy of the oxygen sensor signals received by the engine. As a result, the engine cannot precisely control fuel injection, air intake, and ignition, leading to increased fuel consumption.
