2006 Nissan Pathfinder PO420

Question

I have a 2006 Nissan Pathfinder. The OBIi shows two codes: PO420 + PO420PD. Is there anything I can do myself to clear the codes? Thanks in advance!

Answer 1

There is no information for the P0420D code on the factory service manual, only for the P0420. Unfortunately there is no much you can to clear the code, other tna replace the catalytic converter.
