Ford Fiesta duratec 1.6 2003, check engine light:
I have my check engine light on all time. I've got DTC P0420 for the catalytic converter active. It suggest to replace the converter but, it could also be
the O2 sensor. I have added som pictures to the thread at positions: idle, 2000 rpm and fluxuating between idle and 2000 rpm. Am I misstaken by
beleiving that it might be the B1S2 O2 sensor that is missbehaving? or is the just the catalytic converter that needs replacing?
Hope this is understandable and that someone has a good clue. Thanks in advance
