Default Error Code P0420

Getting this error code with my KK. Looked it up and it would be a number of things. Anyone else had this issue before?

If I’m understanding correctly it’s an O2 sensor error? How many km on the odometer? Petrol I assume?

In that case unless the O2 sensors have been replaced they may be the issue? Totally guessing from the the HO2 front & rear reading text, if I remember correctly there are sensors close to the engine and maybe again after the catalytic converters? Perhaps the converter(s) are expired?? I’m probably not helping at all here. [emoji51]

I guess we won't know now because after starting the car up this morning, no check engine light as if it just fixed itself.. But you could be right, maybe one of the O2 sensors are on it's way out.
