Catalytic Converter Function

Catalytic Converter Function

The catalytic converter is an essential part of a diesel engine. It’s responsible for converting harmful nitrogen oxide (NOx) into less harmful nitrogen dioxide (NO2), which can be released into the atmosphere. The catalytic converter also helps reduce emissions by filtering out soot particles in exhaust gas.

However, if one or more of these components stop working properly, it can cause an emission code to be triggered by the vehicle’s emissions control system (EMS).

Emissions control systems can detect problems with emissions systems and use that information to trigger the Check Engine Light to illuminate on your dashboard if you have this code P0420 – Catalytic Converter Efficiency Below Threshold
