From my understanding, P013E is saying the sensor in the downpipe is not reacting quick enough, is this correct?
so this would mean its not getting enough exhaust gasses right?

If my thinking is correct so far, the sensor needs to be placed closer to the exhaust flow, has anyone done this?

I have the spun metal cat with the J type 02 bung.

I really want to solve this problem, but all zzp suggested was get a tune and have it disabled in the tune, I do not want a tune, so hopefully you guys can help me.

 

I had that code pop a bunch of times last year . It eventually went away and it hasn't been back in the last 6 months or so ..... not a fix but thats how it went with mine.

 

You can get a defouler for it. MPx sells them, vibrant makes it.


Oh and it has nothing to do with how soon it sees the exhaust gases. Dont think that putting it even more directly in the exhaust path will fix it.

 

Well the code is set when its taking to long to detect a change in the exhaust flow after the car is in deceleration fuel cut-off, so that would make me believe it should be closer to the flow to detect the change sooner.
just like if you have a mechanical boost gauge that is on a 20 foot hose vs a 5 foot hose, the closer one will detect the change a little sooner
I am not trying to say you dont know what your talking about, just simply stating my point of view and thinking, and I am looking for a valid argument as to why I am wrong , and as to why moving the o2 sensor farther out of the flow will help solve this problem.
Thanks for the replys guys

 

nobody?

 

Get a Hahn. I regret not having splurged a little more for one. Mpx catted throws codes too.

 

well i kinda have the zzp now, so i gotta figure out how to solve my issue unfortunetly

 

There is no fix. Tune or get rid of it.

 

or grab a $20 defouler and see if that helps your problem... Or drive with a CEL.

 

this is ridiculous

 

You can't add a defouler. There's already a defouler tube, and really, that's the problem. It's too long, and it's getting too little airflow, probably under light cruising conditions.

If it's too short, like an MPx catted, you get P0420. If you add a standard defouler, you get P013E. Go ahead, ask me how I know.

 

i had the defouler and took it off. instead of the 1 code, i got 3 other codes and my RPD stopped showing the AFR. took it off and went back to 1 code with RPD working fine. don't waste your money.

 

tune


/thread

 

i had a code from ZZP's catless but thats normal wit no cat...just clear it...whats the worse that can happen lol

 

well thank you to the people who took the time to read into my problem, and put more thought in, than just saying get a tune, or it cant be fixed,

Since zzp wont do anything for me, looks like I am going to have to look into getting the o2 bung shortened

 

But that IS the best solution.

 

no the best solution is to find a sweet spot where o2 will throw no codes under normal operation conditions, then if a cat goes bad, it will throw the inefficiency code, and if a cat gets clogged, it will throw the delayed response code, getting a tune not only risks voiding the warranty unless you get 2 computers for your car, but it will cover up the problem, and will stop the engines computer from telling you whats going on

i know theirs people who will say oh well if your gonna mod it you gotta tune it or have cel's but that is a bad way to think, and proper placment of the o2 will allow the engine to still monitor it's cat function

 

David, I don't disagree in the slightest, however, the fact remains that the only known catted downpipe which doesn't have this issue is the Hahn DP. They tuned the length and angle of the defouler tube just right. You can try to shorten it, but who knows what the right length is.

 

Ugh, yeah, i might try putting the o2 right by the 90 bend, and if it throws the po420, then il get a defouler, i wish I could just return it and go hahn, i was originally going to get hahn, but I wanted to get the zzp upper charge pipe, so i decided to get their downpipe too

 

How long have you had the downpipe? Like i said.... it will eventually go away and not come back. It took like 4 months and popped that code maybe 5 times total.

 

If you want to try the defouler, don't get the Vibrant J style one. You'll throw P013e. It's too long and not enough airflow under cruise. That's what MPx shipped me to try to fix the P0420 code.

You want a slight angle, straight tube. Look at the Hahn for guidance. You don't want the tube to be parallel to the ground. That's bad for the sensor. Good luck on getting this to work. I gave up.

 

I'v had the downpipe for a few weeks i'v seen the code over ten times

 

i have the same downpipe as you
drive it for a day the code will go away...
it happened several times - i too called onstar to ask, same code, emissions- don't worry about it.

 

the light will not go away, after i clear it it will come back, the same day if i drive it enough, and the code will never "go away" the light may shut off for you, but everytime that light comes on that code is stored in your computer, so you probably have the code stored a bunch of times, this design flaw may prevent you from noticing a more serious engine problem, since you will see the cel light and think its just your downpipe, if they designed the product as well as hahn did, then you would have a perfectly functioning car, that can still monitor cat functions

 

Man, oh man.......you must drive somebody at home really crazy.
