H O N D A, oh how well love it when we smokin V8s, all day, every day, it dont stop, Im rolling in my Honda like Im running from the cops.
BUT Now you know, cause you're Jon Doe, in a black bag, a tag on your toe, I built the Honda, I felt the pain, you're victimized with no one to blame, you're just another victim kid.....
now if I only had a cat....
I just have a test pipe so my sensor would be dragging on the ground
dammit...
I have a sim too but it just dosen't work... I get "p040 2nd sensor heater circuit malfunction" or some crap....
the car runs fine but the CEL light sucks...
what it does is space the sensor out from the main flow of the exhaust stream
and in doing so slows the readings from the o2 sensor , which is the way it should read is slow voltage flucuations
some of the high flow cause the after cat o2 to read fast like the front o2 which sets the code

Your right. & it works. Great for people who have a gutted cat or test pipe.

so what does it do to affect the performance of the vehicle...i understand the concept of it not being in the direct stream of the exhaust flow...but how does it make it run after doing it? and does my new magnaflow cat which is being shipping to me now have an o2 sensor bung?

You dont need it if you have a working cat. This keeps the ECU from detecting a high voltage signal from the downstream O2 sensor & kicking the CEL on & puting the car in LIMP mode. In LIMP mode the ECU trys to coprrect the problem till the 2nd O2 reads correctly. Which it cant do.

I'll get my car to a muffler shop to make them drill a hole and install a nut (that I found after going to 3 stores...
) I'll see if it will still throw me a code once the O2 sensor is back on (I have a magnaflow Hi flow cat) If it still give me a code I'll try this thing....
well that answers that. thanks

the after cat o2 doesnt do much on our cars other than moniter the cat , and set the light
no real side effects

You do not have ot have a cat to do this. I do not, but plan to do this.
The WRX's have one of these made for them, that does the same thing. My friend with his STI (ex J owner has one), works great!!!!!
thanks for posting that!!!!!!!
There is no reason for your sensor to drag the ground unless your exhaust is mounted poorly!!!

Well do this & you wont have a light. Would you rather see the light come on when somethings going wrong rather then the light always being on & something happens & you not know about that 2nd code?

i get code P0420 somethign about catalyst threshold bank 1?? any input.. i like to get ideas before i start buying parts and doing work.

I was getting that, do this cheap $4 mod. It works I have it done to mine.

I've got the same code: P0420, I have a turbo with no cat. Maybe I'll try this mod....

Yes this should work for you.

John Higgins: Thanks for the help, does the thread on the spark plug things fit right into our o2 bung or do we need to make changes?
damn, im happy im not the only one that was throwing that code! haha

Yes it will. It is 18mm. Also the one you drill out, you need to go to a drill bit bigger than 1/2 (can't remember the size). Our Sensor is fat on the end, the 1/2 inch bit does not make it big enough.

Also i have one of these made up ready to use, I will sell. I will take pictures later.

i had my muffler shop just do mine today.. so far no code
ill keep it posted
my magnaflow decal gives me 100 hp!
