Hi Viewers,
I am sharing this video on how to diagnose a bad catalytic converter based on my personal experience. This video will show you the basic concept of using an OBD-II scanner to diagnose an inefficient/bad catalytic converter.
please feel free to ask any questions in the comments sections.
Enjoy
Thanks

Can you please confirm if elm327 genuine works with your lancer? I have heard one needs openport 1.3d for this? can we get live data through elm327 on the lancer? Can you also confirm where you purchased the elm327 scanner as there are a lot of them that don't seem to work? Btw my lancer is a JDM 2006 Lancer, many of the parts are interchangeable between this generation so I am assuming our ECU won't be much different from the US ECU.
Thank you ,your Tutorial Helped me to understand how to diagnose my problem
AfzzaMoto, I looooove this catalytic converter tutorial, very awesome! I have a question: Do you diagnose the cat converter why driving or in park with the engine run?
I have a question. Is the Catalytic Converter welded on to the header? I need to replace mine but I'm unsure it its bolted or welded.
