Hello everyone, I bought a 2012 Chrysler Town & Country with almost 120K miles on it.



Shortly after buying it, the T&C threw a P0430 code. So I changed the Oxygen Sensors and the code came back on. I then changed the Catalytic Converter, and the code came back on again. The car is now just a little below 122K miles.



What would be some ideas for next steps? I have about 7 weeks until I have to do an emissions check, so there's time...but I'd really like to solve this issue ASAP as it is driving me crazy.


Thanks!

 

I am having the same issue. It might be because of the car running rich. Get the car tested for cylinder burn profile. In my case the P0430 comes and goes, but it is driving me nuts too.

 

my past experience with my 06 says it IS the cat... when 420 or 430 pops up it almost ALWAYS is... i learned this years back from several really sharp mechanics....how much oil does it use? mine went at 60k... dealer changed out cat under fed warranty and i had tech friend change out valve seals....that slowed down the oil consumption but still burns a little.. however it has 207000 on it so normal and the replaced cat is still going...dont forget u must clear those codes after replacing the cat... but should clear itself after 20 or 30 restarts...
