How Often Should a Three-Way Catalytic Converter Be Cleaned?

[VonCaleb]

A three-way catalytic converter should be cleaned every 30,000 kilometers. If you notice increased fuel consumption or reduced power, it's necessary to inspect and clean the catalytic converter as needed. Whenever you perform maintenance tasks such as cleaning the fuel injectors, throttle body, or intake tract, it's advisable to clean the catalytic converter at the same time. Additionally, it's best to clean the catalytic converter before an annual vehicle inspection to ensure smooth passage of the emissions test. The three-way catalytic converter is an emission control device in the engine, and its proper functioning directly affects the engine's fuel consumption, power output, and emission levels. If it becomes clogged or malfunctions, it can lead to excessive exhaust emissions and negatively impact engine performance.
