Checking Catalytic Converter Efficiency
The converter has an efficiency rating that is computed by the vehicle. This number rates the amount of reduction that is occurring in the converter and its ability to store oxygen.
Diagnosing Catalytic Converter Failure Symptoms
Although construction can vary according to engine application, the common three-way catalytic converter contains a reduction and oxidation stage. To create maximum surface area, each stage is generally a Âceramic or stainless steel honeycomb substrate covered with a rough silica and alumina wash coat. Both stages of the converter are coated with precious metal catalysts

Component Connection: The Science Behind Catalytic Converter Diagnostics
Although modern OBD II technology has simplified catalytic converter diagnostics, it’s still important to understand the basics of catalytic converter operation when dealing with a P0420 or P0430 diagnostic trouble code (DTC).

Converter Codes: How Long Will The Light Stay Out?
Even if the converter is operating below 95% efficiency or the oxygen sensor is bad, the chances of the light coming right back on are slim. If you clear the code, the light might stay off for a while until the system goes through two readiness cycles. This might take a couple of days or a couple of weeks. But, no good deed goes unpunished because the customer will be back and your quick fix will be forgotten.
