Honda Accord: ThreeWay Catalytic Converters
The three way catalytic converters contain precious metals that serve as catalysts, promoting chemical reactions to convert the exhaust gasses without affecting the metals.
The catalytic converters are referred to as three-way catalysts, since they act on HC, CO, and NOx.
Replacement units must be original Honda parts or their equivalent.
The three way catalytic converters must operate at a high temperature for the chemical reactions to take place. They can set on fire any combustible materials that come near them. Park your vehicle away from high grass, dry leaves, or other flammables.
Defective three way catalytic converters contribute to air pollution, and can impair your engine’s performance. Follow these guidelines to protect your vehicle’s three way catalytic converters.
Always use unleaded gasoline.
Even a small amount of leaded gasoline can contaminate the catalyst metals, making the three way catalytic converters ineffective.
Keep the engine well maintained.
Have your vehicle diagnosed and repaired if it is misfiring, backfiring, stalling, or otherwise not running properly.
