Diagnosing Catalytic Converters

Diagnosing Catalytic Converters

There are multiple steps to diagnose a possible air-related issued on a catalytic converter.

In this video, we discuss some diagnostic procedures for catalytic-converter problems arising from issues relating to air, in our air, fuel and spark conceptual grouping.

The first step is to perform a visual inspection for worn-out gaskets and vacuum leaks. If a vacuum leak is suspected but not found, perform a smoke or soap-bubble test.

Detecting Leaks in AC Systems

A vehicle’s air-conditioning system operates in a closed loop, meaning that the refrigerant recirculates on a constant path through the same components to cool the car. 

If the system is functioning as it was designed, there shouldn’t be anywhere for the refrigerant to escape. So, if the A/C system isn’t cooling the car, it’s a clear indication that there’s a problem – most likely a refrigerant leak.
