I have a 05 with 5.7 hemi and the codes 0404 and 0420 are being shown. anyone or someplace on here that can i find the answer for these? also what's a good brand name for cleaning the TB?

 

to the top!!!

 

"P" code?

P0404 = EGR Position Sensor Performance

P0420 = Catalyst Efficiency

Codes in FAQ:

Thanks for the find. I think i'll clean egr valve and see if that helps, if not i'll just replace it. will carb cleaner work pretty good or should i use something else?

 

On second thought, do NOT attempt to download the file, it seems that the file hosting/transfer link has been hijacked. I just tried twice and had **** sites pop up on my screen along with a Norton's security risk that there was an attempted attack to my PC. WTF. Anyway, I have PM'd the moderator of that thread to alert him that something just isn't right.

 

Here's a DIY for TB cleaning for ya:
