3 Common Problems with Catalytic Converter

What is a Catalytic Converter

Catalytic Converter

A catalytic converter is a valuable part of your vehicle. The device essentially acts as a filter to sift out harmful gasses from your cars exhaust. The long tube connects from your engine to your exhaust with the converter placing itself in the center. Using a ‘honeycomb’ structure within the shell, the honeycomb can filter our carbon monoxide and other harmful emissions. This is the most valuable part of the vehicle regarding reducing greenhouse gasses and is a necessity for passing emissions tests.

But with such a valuable piece of machinery comes a very valuable upkeep. This is an extremely important part of the vehicle, but that doesn’t mean it is free of maintenance. This piece can have problems exclusive to it, and G Exhaust is here to let you know what to watch out for when it comes to keeping your catalytic converter tip top.

Problems of Catalytic Converters

Arguably the most common problem is overheating. Overheating happens when the temperature raises too high due to a failing of the oxygen sensor. The oxygen sensor should be able to trigger air flow that will cool the converter down. However, when this happens, the converter can either shut down temporarily or completely depending on the damage dealt.

A terrifying problem is Matrix Contamination. The converter is only designed to filter out engine oil, if anything ever finds its way into the converter, it can be catastrophic. Whenever there is a coolant leak or any contaminant that might accidentally find it’s way into the oil tract, this causes the converter to filter the chemicals improperly or not filter the chemicals at all.


A final and equally common problem are when the catalytic converter clogs. This most commonly happens when people insert oil of a different grade into their car. The thicker or thinner fuel ends up clogging up the converter and sticking to the webbings of the filter. This can cause a large problem because you might need to replace the converter completely.
