Can the Three-Way Catalytic Converter Be Repaired?

[Grady]

The repairability of a three-way catalytic converter depends on the situation. It can be repaired if it's merely clogged, but not if it's damaged. Here are the details: General clogging can be repaired: If the three-way catalytic converter is only clogged, its performance can be restored through cleaning. However, if the clogging is severe, the repair effect may be poor, and replacement is usually the better option. Common cleaning methods for the three-way catalytic converter include additive cleaning, drip cleaning, and disassembly cleaning. Physical damage requires replacement: If the three-way catalytic converter is physically damaged, such as cracked or deformed, it cannot be repaired and must be replaced directly.
