ok so im throwing the 0420 catalytic 1/1 efficiency code. And i only put on a needswings DP 2 weeks ago... wouldnt it throw it 2 weeks ago?? Do i have a problem? or is it just the aftermarket DP?
My car threw that code a few weeks after I got a new down pipe. I had the 02 sensor wires lengthened to fit past the cat. A quick reset of my computer got rid of the code for as long as I had the stock computer. About 2 months
Ok so here the situation with my code/problem. Was listening to the cd player while painting then my cd player just went out, just shut off. everything works but the cd player. I try to start to car and makes a grinding noise so i stopped trying. I threw a 0108 map sensor voltage high code any help would be great.

Check both headlamp ground connects are attached to the body frame in front of the radatitor.
hey I have this one too.(sorry if this is really late)If im not misstaken its a code you get for having stage 2: or at least thats what it says in the install instructions:
I have Stage 3 and thats the code im throwing, idk if there are other codes because i just reset my pcm by pulling that one yellow fuse, but my car is cutting fuel or something man, like it used to be only at high boost, it starts to stutter then cut, now even at low rpn, and just starting from a stop, it cuts a little ugh my car needs Jesus...or Tom Cruise... PLUS Dodge said im throwing an over boost and my downstream o2 is out, but stage 3 eliminates the downstream o2 and the turbo is bigger duh. if i press the pretty little red button(high octane) it revs a little higher but then does the fuel cut...help? my bro did the fuel pump rewire thing for me(stuff from autozone), and we are about to put that one 255 pump in...maybe i just need to gap my plugs... help!

Good deal. Thanks for this listing. If there are any more please add.
This is now a sticky. It will help out those who throw codes, and do not have a list available.
I have a 0420 code that just popped up, wht does catalytic 1/1 effeciency mean?
Ok well im going to take a wild guess and say you dont have a Cat on right now and that you prolly replaced it with a Needswings or with another aftermarket... and your still on a stock pcm...
Well if this is true then i dont think its really much to worry about... i never did... If you plan on atleast staging to 1 then it wont ever show up again... I think it means that its sensing that your cata has a higher flow then before and the effecincy is being lost thru a "leak" in the exhuast...(again if you have a dump then hell yea thats a huge leak)... but nothing to really worry about...
