Hey Everyone,
So my engine is throwing a code P0420 (yes, I thought it might have the munchies too...). On the list I have, the code reads as 1/1 Catalytic Converter Efficiency.
The code came on yesterday and I reset it and then it came back on today.
I'm guessing it's either the sensor or the cat itself. The truck has 48k miles and is a 2004. Seems soon for the cat to be going out. I just changed the exhaust about a month ago, could that have caused this?
Does this do anything to engine timing or make the truck run rich? Also any tips on how I should go about fixing this?
Any help on this would be greatly appreciated gents.
