Understanding Lexus RX Catalytic Converter Problems
Catalytic converters contain a honeycomb structure coated with precious metals (platinum, palladium, rhodium) that act as catalysts. As hot exhaust gases pass through, chemical reactions convert carbon monoxide to carbon dioxide, hydrocarbons to water and CO2, and nitrogen oxides to nitrogen and oxygen. Modern vehicles have multiple converters and oxygen sensors to monitor efficiency.
Exhaust gases from the engine flow into the catalytic converter at 400-600°F. Inside, the precious metal catalyst triggers chemical reactions without being consumed. Oxygen sensors before and after the converter monitor its efficiency - if the converter is not cleaning exhaust properly, the check engine light illuminates. A healthy converter reduces harmful emissions by over 90%.
Why RXs Develop Catalytic Converter Problems
Staten Island's Verrazzano Bridge tolls can accelerate these issues, making early detection and maintenance especially important.
