Ok so I installed my ZZP catted downpipe about a month ago been driving with that dam light on what can i do. I took it to auto zone they said it was the catalytic converter has failed. So my question is do i have to take my ZZP downpipe off now or what?? Answers greatly appreciated.

 

Black tape mod

 

:/ so theres no way for me to fix is it because i have to pass inspection

 

I wouldn't think that a catted downpipe should throw a code. Have you contacted ZZP?

 

No i havent im going to contact them and see whats the problem is

 

Vibrant Oxygen Sensor Defouler - Universal Exhaust Items

Worked for me.

 

do you have that on both bank 1 and 2?

 

Ok thanks ill try that do i need one or two?

 

I only got one

 

yea put it in the bung after the converter. some of those defoulers r hit or miss. u can get it erased with a tune...

 

Ok thanks

 

and if u need it gone quick u can disconnect/reconnect ur battery and it might go away for a while.

Reason CEL popped up is because its a high-flow cat, and the computer isnt recognizing the extra air flow, thus the CEL.

 

yea i might do that for my Inspection

 

funny this thread popped up, my car is currently at the shop, being inspected, i have zzp's catted dp as well, and yes it threw the code, i cleared the code using my interceptor and sent it to get inspected, but supposedly they still found something in the cars computer, not exactly sure what all went on, the mechanic spoke with my dad and all he said was that there was a problem lol, anyone have any suggestions? my cel is gone but yet they still found something

 

Do PA inspections hook up and read emissions monitors?

 

yep

 

Washers can sometimes help get rid of the code.

 

Just becauuse you cleared the code doesn't mean that the monitors are set. Install the defouler and drive it for a bit.

 

^ This. My zzp cat did the same thing. I got my car programmed and got that code deleted, so I don't have to look at it.

 

X2. It takes 3 full cycles for the monitors to set. If you cleared it right before then they still saw it

 

Thanks for the info guys! How long do you think it will take for the monitors to set once I put the defouler in?

 

Just curious, any chance I can find something similar to the defouler at a hardware store?

 

3 full key cycles so start the car drive for a bit kill it and repeat 3 times. Car has to get to full operating temps too

 

alright thanks!

 

Hmmm, im confused more lol ZZP told me to turn in my ECU. I have no idea how to clear this code now whats going on? Is it a fault in ZZP downpipes or what?
