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...

Hey everyone, sorry for the long post but I wanted to try and include all the details. I currently live in Mexico and recently flew from Guadalajara to Dallas to buy a car and drive it back. I've owned several GC's in the past and absolutely love them, so I knew this is what I was hoping to...

As stated above I've got two fault codes on my 1999 Plymouth Voyager (base) with 2.4 liter 4-cylinder engine. The van runs well but burns an appreciable amount of oil; roughly one quart every 400 miles. I've owned it not quite a year now. During the winter, in cold weather, the "Check Engine"...

Hi, I am new to the forum. I have a 2008 Chrysler Town and Country Touring with 3.8L OHV Engine and 113k miles. I should prefix this post by saying that this van/engine has been always burning oil at a rate of about 1qt. per 3k miles at 20k miles and a rate of 1qt. per 1k miles now (113k)...

{Warning: this will be a long-reading post as I want to detail as much as I can for context.} Vehicle: 2006 Grand Caravan SXT, 3.8L, ~122K miles, Stow'N'Go. Van threw the lovely P0420 code yesterday. Did research for testing for confirmation of a bad catalytic converter and was ready for my...

so i got the P0420 code - "Catalyst System Efficiency Below Threshold".. spent a morning at the dealer only to find out "not covered by lifetime extended warranty" (going to be $600+). and this 3.8L has always burned oil. After changing the valve seals (big job) and the PCV (very tough to...

thanks for reading this. 06, 3.8. hit the pedal to get speed up yesterday. 5 mins later get code light on. reads p0420. 88,000 miles on van. is it worth me buying 02 sensor (bosch, ntk options at advance a) for the front/upstream i believe represents upstream. i don't have a visual meter to...

First time poster to any type of forum, so forgive me if I'm doing this all wrong. 2009 T&C touring with the 3.8 and 6 speed trans. Throwing a P0420, P1128 and P0339 code. I can clear them with a scanner, and sometimes they'll clear themselves overnight...but all three come back after 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 a 2006 T&C with 3.8L - Here is the history on this - I have been battling the P0420 code for a while - so I ended up replacing all the following within the last 6 months - only to have the P0420 code keep coming back. I have replaced the following: upstream & downstream O2 sensors, MAP...

Hello everyone - I got a P0420 ( Catalyst System Efficiency Below Threshold Bank 1 ) a while back - so i replaced the front and rear o2 sensors and did a good tune up on the van - with new EGR valve spark plugs pcv the works. Code stayed off for maybe a month - then back on - finally after...
