P0420 is likely a vacuum leak, not a PCM issue. Check your vac hoses and replace if needed, the car is twelve years old by now. Other possible sources of vac leaks include the EGR passage, the S/C gasket, and the boost bypass valve.

Uh p0420 is the cat code bruh. Bad/clogged cat,or failing o2 sensor. Or even having a high flow cat.

Sounds like you need the code deleted.

i bought my 01 with an intense PCM. the p0420 code came up and i deleted it and it never cam back again.. I'm not sure if the pcm did something or i just got lucky... just putting it out on the table
