O2 Simulator

Greetings,
just bought a 2002 regular cab, 2.7, 4x4. It has 175000 miles on it. The cat is going and replacing the downstream sensor only kept the light off for about 5 miles. I'm really not interested in replacing the cat right now as it will likely end up that I'll replace the entire, cat back, exhaust system too, which I really don't want to do at the moment. I'd like to get a replacement for the sensor, which will allow me to get this inspected, and then deal with the exhaust next summer.
Anyone know the proper name/part number/source for the "null" sensor? Alternatively, can you direct me to a thread that discusses it?
Thanks!

Thanks! Exactly what I need! While we are at it, do you know of anyone who does a "Test Pipe" cat replacement?
Thanks again!

 

I got URD's O2 sim on both my toyotas. Works flawlessly.

 

Can you unbolt yours and clean it out? It might be unreasonable if it is real rusty, but it'd be free.

 

This might work. I used this trick on an 05 GTO and it worked like a champ...

I believe URD sells both the test pipe and O2 sim. I welded up my own test pipe and have the sim. No light anymore!

 

Does this really work on our tacomas? I keep seeing this and kinda pissed I spent so much on the simulator when I coulda done this for $5
It still doesnt help the fact that something is wrong and needs replaced but...

 

Not sure, but it worked on my mk3 Jetta.

 

Yup, it did work on my GTO, that much is for sure.
