Hello,
after P0420 code, I think I will have to replace the catalytic converter. The error is "catalyst system efficiency below threshold bank 2".
I understand this may be also caused by faulty sensors, which I ordered - upstream and downstream, but in case the trouble persists, I want to know what I need to buy then. From what I found online, there were various converters for sale - "front", "front left", "front right" etc. Also I was unable to pin down the exact part number - the closest I got is "CA01-20-500A" and "CA20-20-500".
My question: if I understand it correctly, there are 2 cats there? Which one should I replace? Or do I need to buy more than one? The "bank 2" should be cylinder 2, correct?
Can I on basis of this "bank 2" error somehow find out which catalytic converter is faulty?
Thank you so much for any help.
