Will There Be Any Impact If the Three-Way Catalytic Converter Is Broken and Not Replaced?
1 Answers
The three-way catalytic converter, when broken, does not affect the normal operation of the vehicle. However, it can lead to difficulties in ignition, reduced driving power, engine backfiring, increased fuel consumption, incomplete combustion, carbon buildup in the cylinders and spark plugs, among other issues. Prolonged neglect can indeed have adverse effects on the car. How to Determine the Condition of the Three-Way Catalytic Converter: Visual Inspection. Examine the exterior of the three-way catalytic converter for any damage or discoloration. Scratches, cracks, or other visible marks may indicate prior damage. If there are noticeable gray spots on the protective cover, severe discoloration, or purple marks on the shell, it could suggest overheating issues. Check the Engine Exhaust. Place your hand near the exhaust pipe outlet to feel the exhaust flow. This helps determine if the catalytic converter is clogged or if there are exhaust flow issues. Another method is to open the air filter, remove the filter element, and observe if there is exhaust backflow during rapid acceleration, indicating poor exhaust flow. To assess the TWC's condition, also check if the secondary air injection pump is functioning properly. Use an Infrared Thermometer. Compare the temperature difference before and after the TWC using an infrared thermometer. If the temperature difference between the inlet and outlet of the catalytic converter is less than 10°C, the TWC is likely damaged.
