Honda 18160-P28-A10 Converter (Dk)

Due to Federal warranty covering emissions control components including the catalytic converter, it is recommended to contact a dealer service department before replacing the converter at your own cost. The catalytic converter is an emission control device added to the exhaust system to reduce pollutants from the exhaust gas stream, with two types available: The ordinary oxidation catalyst that helps in reducing the hydrocarbon and carbon monoxide emissions and the three way catalyst which reduces the emission of oxides of nitrogen, hydrocarbons and carbon monoxide. The diagnostic tools for a catalytic converter are costly and specialized and if there is any doubt, it is advisable to take the car to a dealer or an emissions testing center for evaluation and repair. When the vehicle is lifted to work on the underbody, it is necessary to inspect the converter for signs of leakage, rust, dents, and other forms of damage, including the welds and flange bolts that Although catalytic converters do not break often, they can become plugged, and the easiest way to check for a restricted converter is to use a vacuum gauge to diagnose the effect of a blocked exhaust on intake vacuum by opening the throttle until the engine speed reaches about 2000 rpm, then releasing it quickly; if there is no restriction, the gauge will quickly drop to not more than 2 in-Hg above its normal reading, while a reading of 5 in-Hg or more above normal, or a momentary hover at the highest reading, indicates that the exhaust system or the converter is plugged, or that an exhaust pipe is bent or dented, or the core inside the muffler has shifted.

Periodic inspections of the heat shield for cracks, dents, and loose fasteners are important to maintain the integrity of the exhaust system.
