How is the efficiency of a catalyst demonstrated?
The catalyst’s efficiency is demonstrated by its ability to oxidize CO and hydrocarbon emissions. The Powertrain Control Module ( PCM) compares the output signals of the front and rear oxygen sensors to determine whether the output of the rear sensor is beginning to match the output of the front oxygen sensor.

What does a catalytic converter do on a Kia Soul?
Catalytic Converter – A catalytic converter is responsible for scrubbing out as much pollution as possible from the Soul’s exhaust. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.
