Guys ive just had the code 0420 throw my CEL. 350z tech code list says catalyst system bank 1. I have High flow cats on the car but have never thrown a code before.

Im i ok to just wipe the code as it is because of my cats?? Or do you think i will need to replace a sensor or take it in to a dealer to look at it in more detail??


Thanks for the help guys.

 

I'd clear it and see if it comes back.
