Hello,
I own a 2015 Opel Meriva 1.4 Turbo (gasoline) with 200,000 km on it (~124,000 miles).
The car was converted to LPG (aftermarket system) quite some time ago.
Recently, I connected a basic OBD-II scanner and it showed fault code P0420. I took the car for a short drive to try and determine if it's a faulty oxygen sensor reporting incorrect values or a defective catalytic converter.
I've attached the graphs I was able to extract from my basic scanner, hoping the values it reports are accurate.
Could you please help me diagnose the problem? Any assistance would be greatly appreciated!
I'm not sure if it's related, but I wanted to add:
* The engine mounts are worn, and I plan to replace them very soon.
* Occasionally (rarely), the engine shuts off unexpectedly, usually when idling or driving very slowly.
