P0420 error code
Discussion
Hi everyone,
I keep getting an ODB error code / message (P0420) since a few weeks.
My lambda sensors are new, and I'm now considering a cat defect.
But before I buy a new cat I would like to know if one you has another diagnostic.
Therefore I thought I should print out the report I get and show it to you. This report shows figures prior to engine ignition.
What I also put below is a live feed from the bank 1 sensors while driving with the car.
If one of you sees where the error comes from, I would be infinitely grateful
!!! What I understand is that the issue doesn't come from misfires.
Could it come from my bank 1 sensors as both seems to be totally unstable?
Finally, is there any particular risk for the rest of the hardware if I keep driving with a defect cat ? In other words, should I replace it asap or can it wait?
Thank you in advance for your help.
