Message:
Ok so my truck thought it would be fun to throw this code out last night. Something about an inefficient catalyst or what not? Anybody else have this problem? I'm thinkin maybe my catalytic converter died or something. I replaced my O2 sensor not too long ago so I dont think that's the problem. I have a superchips and am currently running it on the peroformance mode w/ 92 octane but on this last fillup I went with 89. Could that be a reason? Any help would be much appreciated. Thanks.

Just got a book today with the codes in it. P0420 reads (Catalyst System efficiency below threshold) (left cylinder bank). Hope that helps.

Message:
The Powertrain Diagnostics manual states the reason for the condition is the difference between the pre and post cat O2 sensor readings are too close together. (Meaning: the sensors are not measuring properly, or the cat isn't working.) Possible causes are worn out sensors or degraded cat.

The first thing to check/replace is the sensors. You must change both, not just the post O2 sensor. Otherwise, you'll run into other O2 sensor codes.

The expected life expectancy of an O2 sensor is between 80-100K miles.

What year / engine do you have? Is it a California or Federal emssions truck? How many miles are on it? Are they the original sensors? Etc.

What's your left foot doing?

I replaced my o2 sensor after the cat probably about 4-5k mi ago. I dont think my truck is cali emissions but I'm not sure. I used to live in oregon and that's where I got it. Right now I have 116k on it. '00 3.9

I have read from a few sources that if both the pre and post sensors don't get changed together you will often times get the P0420. Change your front O2 sensor, clear the code, and if it comes back then you might address the cat.

I erased my code a few days ago but I havne't done really any driving yet to see if it comes back. I hope it doens't because I really dont want to spend the money on another O2 sensor...but hey if I have to oh well. Thanks

I got a '96 Dakota 3.9L, it's only got about 70k miles now, but when I first got it 55k miles, the cat was broken apart inside. With the engine off, "cat" cool, smack with a mallet of sorts, if it rattles I'd go with replacing it. I put on a Hedman- high flow cat, could tell the difference running right away at higher rpms, also. No problems with eng.light before or after.

Oh, if it's OBDII you're emission legal, but you'll have to do a decent amout of driving in several different situations for it to completly clear. There is a whole process in the computer that needs to be met.

most common fault is up stream 02 the one befor cat has gotten lazy.... thats the 02 that does more work cause of its heater circuit.... try replacing that one.... if it doesnt help then your cat has gone bad and needs replacing.... theres not a whole lot of test for that code... its ethier bad 02 or bad cat....

I had that code on my '06 4.7 HO AWD. Had p0420 and
p0430(both banks). It caused me to fail aircare. I had it in the
shop and was told that I probably need to replace both cats.
The thing is, I also have an exhaust leak at the manifold. I
understand that this can also trigger those codes. They
cleared the codes and sent me on a long drive. I then passed
aircare as the codes did not return yet, but I know they will.
Can anyone confirm that the exhaust leak can trigger these
codes?

I have a 06 Dakota 4.7 I'm at 154,000.
I've been dealing with this code for two
weeks now, it's read a p420,p430 and a
p340 which is no camshaft position sensor
circuit failure I've replaced the camshaft
sensor. Unplug the battery drove 50 miles
and it came back on I really don't want to
spend $350 on a cat I ran seafoam through
my gas tank and the codes didn't come on
until I put it in could the seafoam be
triggering the codes or is it either O2
sensor or cat? If any one has any ideas
please help or has figured out problem
I'll take input. Thank you

Message:
Well, you could go changing parts first, but I recommend you check the exhaust manifold for leaks first. These engines 3.7,4,7, are notorious for gasket and warped manifold leaks. This sends a skewed O2 level through the first sensor, which affects the second sensor reading. I replaced both sensors before testing for leaks, and the code was still there. To test for leaks, seal a shop vac hose to your exhaust pipe with a rag. Put the other end into the "exhaust" port of the shop vac. Turn it on, and spray a soap and water solution around the exhaust manifolds. Any leaks will make bubbles. If you're lucky, it's just the gasket. Oh, and if you do replace O2 sensors, make sure they are the same brand as original. I used NTK, thinking they were the brand, and it threw "O2 sensor heater circuit" codes. The ECM is sensitive to the resistance in the heater circuit. If you choose to put off the manifold or gasket replacement, you can buy "spark plug spacers", drill it out to fit the O2 sensor, then install behind the cat. This takes the sensor out of the direct exhaust stream, and should solve the CEL, temporarily.

165k miles just replaced b2s2 and b1s1 o2
sensores i got a cheap ultra power in the b1s1
spot and a NTK in the B2 S2 spot.i first
replaced both sensors on b2 with cheap ultra
powers from rock auto just to fined out the pcm
does not like the voltage they give out and
they are lazy and junk. so i spent more money
and got the down flow NTK i know i still have
to replace the up flow sensor. or with all that
said. im still getting a evap code and the bank
2 catalyist codes but i know its the o2
throwing the cat code. but my fuel mileage has
went bad fast and the idle is so bad you
can watch your drink vibrate in the center
console when at a stop or parked. also my
throttle response and power when WOT some times
it will want to roast rubber and other times
its a turd.. new tps as well.. the only
time i see a power and mpg change is when i
reset the computer. negative battery post then
turn key on blah blah blah yes i go threw all
of that and its like a brand new motor all over
again....for about 50 miles then same thing....
this is only me clearing the codes with a obd2
scanner not a full reset....check out my

Dakota Orsbor, You can take your Dak into the
dealership and they can pull any open recalls
still left for you vehicle, they do this by
pulling the VIN from your vehicle and they can
look at any history that they have of it. It is
all checked for free, and done for free. Just
gotta getter done!
