I have a 2002 Volvo S80 T6 and the CEL is on. I don't know what I have to do to fix it. I could get a new catalytic converter, but I am hoping something else is throwing the code. I keep hearing all of these different solutions and I am extremely confused. Does anyone have some experience with these codes? By the way.. I have two O2 sensors on the CAT and two sensors in the front.
Thanks a lot,
Bronson
PO422/PO420... could it be an O2 sensor?
