As long as you don't plan on removing your rear O2 sensor, it will work beautifully. I ran one and had no problemos whatsoever.

How much are they? I have the same code right now P0420 and dont wanna buy a new cat.:shrug:
EPaO makes a more expensive one but it's plug and play and you can remove the rear o2 sensor. That's what i bought.
have the link and price for the one u say is plug and play
the urd one is 75 price isnt bad
but plug and play would be nice

i plan to remove my cats and go straight pipe as well, i have the epao plug and play but havnt installed it yet. epao seems like a good company, they offer lifetime warranty on their products (i think) and you dont have to cut into wires.:waytogo:
Heres the EPaO sim:

Now i like URD for alot of things, but i believe this one in the superior product. with the URD you need a working rear o2 sensor. for my engine swap, i'd need to install an additional bung in the exhaust and purchase a new o2 sensor, plus the sim, would have cost much more and been alot more work that this plug and play unit.
My 2 cents.

Rear O2 Sensor Simulators are used in off road/racing vehicles to prevent the check engine light from illuminating and to prevent an ECU code from tripping. URD Rear O2 Sensor Simulators are carefully calibrated to condition the signal from the rear O2 sensor to keep it in the range the ECU is expecting to see. DO NOT USE ON A PUBLIC ROAD OR HIGHWAY ANYWHERE IN THE UNITED STATES.
Note: Be cautious of O2 sims that replace the rear O2 sensor with a falsely gererated signal.
Toyota started using a wideband type O2 sensor (air/fuel ratio) in the front position for better engine control. These wideband type sensors need to be recalibrated from time to time by the ECU. The ECU uses the rear sensors for this recalibration process. The ECU cannot properly recalibrate the wideband sensor using a falsely generated signal. This process is explained here, US Patent 5706654.
Use only a URD O2 Sensor Simulator on these vehicles to avoid poor performance, drivability issues and poor MPG.

has anyone who removed their cat and ran no sensor or replaced their sensor with a plug n play experience this recalibrating from time to time?http://www.urdusa.com/index.php?cPath=66_170&osCsid=p77ahtl10f2q7e37c9asqq5bk1

my CEL just came back on today on the way to work after about 300 miles of driving..im pretty sure that it is not the o2 sim i might just have a leak..
mine came on about two months after I installed the 02 sim and I cleaned my MAF and that fixed itmy CEL just came back on today on the way to work after about 300 miles of driving..im pretty sure that it is not the o2 sim i might just have a leak..
I was freaking out thinking that the sim quit working:lol:
FYI- Most of the URD Rear O2 Sims are now Plug-N-Play.
It takes about a full minute to install the dual channel versions. Just unplug the stock O2 sensor, and plug a plug from the URD sim into the sensor and one into the vehicle harness.

^^ Trick, nice.
I have seen this a/f sensor calibration happen myself, so a delete will not be good for certain models,
