what a Christmas gift , got the check engine light his morning p0430 .searched the forum , code means my precat is bad . this isn't my original one I recently baught it cause mine cracked and couldnt be fixed changed 02 sensors and all of that . I hate seeing check engine light on my car I don't need to pass emissions or anything but what can i do to fix this code either upgrade to header or anything that will just get rid of this

p0430 is bank 2 so it's the front cat that is bad.


I used a extension, or you can solder a little circuit board to your harness.
Whatever is good for you.

Wouldn't using a o2 sim for the rear o2 sensors work?

where did u get that from and does it go in without any modifying

The ideal way to fix this: 3 options:
Replace the precat : expensive (OEM cost: $599.00 parts only& aftermarket cost: $299.00 )
Install headers+ 02 Sim or nonfouler
Gut both precat:
Precat near the radiator and precat near the firewall. Install 02 sensor nonfouler to the two secondary 02 sensor. Dont fix the 02 sensor,that specific code means a clogged precat or a deteriorating precat that eventually messed up the engine, you need to replace, gut , removed it and install headers.

ebay.
o2 sims or non foulers. You'll see them.

Screw it in, reset code, don't worry about p430 again.

i listened to you guys and installed the non foulers check engine light has been gone for about 190 miles . i didnt get a chance to punch out my precat in the front . scared its going to mess up my motor , heard bad cat could do that . i am thinking of getting warspeed ypipe instead of punching out rear precat (bank 1 by firewall) but would i get a check engine light if i install the y pipe, and where would bank 1 sensor 2 go . thanks for anyhelp guys .

That's exactly what you should do if you don't care about headers. The front cat will just fall out, usually. ****ing junk!

Most people have CELs, some don't. I would say since you already have one that it would persist. Try the defouler on the new Y and see what happens. If that doesn't work you can extend it or use an angled one. Worst case is O2 sim, but they're so easy to wire up and work like a charm.

He's gouging a bit though. Was about $100 cheaper yesterday, but it will still sell out fast.

damn these prices today are still high for these cars .
i might as well just gut precat and use warspeed y pipe .. is the rear cat in the back really needed ?not talking about the precat .Cali spec

Delete all the cats if you can get away with it where you live.

shawniiebwoiiee

would that cause any problems

What does the extension do to cure the code?

shawniiebwoiiee

it basically spaces the o2 sensor out from the exhaust to trick the sensor into thinking that the cat is fine
