Long story short, I bought an 09 T&C 3.8L with a hollowed out catalytic converter. Obviously, because of this, it throws a P0420. I would like to get the light turned off so that my wife can use the remote start. I have already tried a non-fouler to space it out, with no luck. I appreciate...

Hi everyone, I recently put a ton of work into my van, but two days ago it refused to start. I’m less upset about the issues it has now, because I just learned that the Dodge dealership my husband’s aunt got it from rolled the odometer back and lied to her about it. It has 197k, not 168k. I had...

I've got a 2007 T&C, 220k miles, with a plugged cat. I'm considering either replacing it or, *cough* not replacing it *cough. It looks like there are some methods to trick the computer into not throwing a P0420 by using a couple of spark plug defoulers to raise the trailing O2 sensor out of the...

I need some help. Four months ago, I changed the Catalytic Converter and both O2 sensors with Chrysler parts. Everything was good for three months, now the P0420 is back. Any ideas? The 2006 has 152K miles and is on the second CC. I have one of those 3.8's that burns lots of oil and the CC...

I have an 06 T&C 3.8L and its been throwing a P0420 catalyst system efficiency below threshold bank 1 code. I have replaced both front and back O2 sensors after reading that the code could be the sensors & to try that first to see if its just the sensors. I did a big tune up while replacing the...
