Hi everyone,

I got my code pulled from AZ tonight. It's PO420 which seems to be the 02 sensor from the cat. Any ideas on what I should do? Thanks in advance.

There is a bulletin for ECU reprogram from Nissan, call up the local dealer and see if its covered still. Its code P0420 that the bulletin applies to. Unless ya removed your precats then U are screwed and need to get a www.o2simulator.com to fool the ECM into thinking the cats are still there I used to see that code on daily basis on my Maxima when I removed all my cats.
