Three Way Catalytic Converter The three way catalytic converter contains precious metals that serve as catalysts, promoting chemical reactions to convert the exhaust gasses without affecting the metals. The catalytic converter is referred to as a three-way catalyst, since it acts on HC, CO, and NOx. A replacement unit must be an original Honda part or its equivalent. The three way catalytic converter must operate at a high temperature for the chemical reactions to take place. It can set on fire any combustible materials that come near it. Park your vehicle away from high grass, dry leaves, or other flammables. 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 converter ineffective. Keep the engine well maintained. Have your vehicle diagnosed and repaired if it is misfiring, backfiring, stalling, or otherwise not running properly. U.S. model is shown. TOC The 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. Technical Information 2014 Insight 389
