Understanding Your Lexus RX 400h Catalytic Converter
The Lexus RX 400h catalytic converter transforms harmful gases—NOₓ, CO, and HC—into benign N₂, CO₂, and H₂O using precious-metal catalysts. Positioned between the engine and exhaust, it sustains fuel efficiency and ensures you meet stringent emission regulations. For an in-depth look at emissions control components—including EGR, catalytic converters, and DPFs—see this emissions control systems overview.
How It Works
At high temperatures, exhaust gases pass over platinum, palladium, and rhodium washcoats inside the converter’s monolithic substrate. These catalysts trigger oxidation and reduction reactions that neutralize pollutants. A failing unit can trigger P0420/P0430 fault codes, reduce acceleration, and raise fuel consumption. Learn more about catalyst substrate design on monolith catalyst supports.
Common Replacement Signs
- Persistent Check Engine Light with P0420/P0430 codes.
- Noticeable power loss or sluggish acceleration.
- Rattling noises under the vehicle from a broken substrate.
- Failed MOT emissions test due to high pollutant levels.
- Rotten-egg sulfur smell during cold starts.
Maintenance Tips
Extend converter life by using low-sulfur fuels, performing timely oil changes, and addressing engine misfires promptly. Regularly inspect oxygen sensors to prevent overheating and avoid short trips that prevent the converter from reaching optimal temperature.
