I e-mailed the people at o2 simulators they told me you can use the LEXUS 2004 and up o2 simulator on the tC. They told me the people who have ordered it never called back to say it doesnt work. I dont see why it wont turn off the CEL when you have an aftermarket header. It just simulates that the cats are there and working. They are selling it for $40.00 I think I might have to hit em up. I was also wondering if anyone has tried this yet. Let me know. THX

sounds like a cheap gimmick they are selling for an outrageous price..

you can buy something at the hardware store for $5 and it'll do the same exact thing...

I tried the anti fouler trick CEL came on 200 after

well... i wouldn't waste my time with a site like that...
fyi.. you spelled it wrong.

I just think with the o2simulator it would be a more permanent fix.

Sorry it was o2simulator.com

well here's the thing.. if the thing actually worked.. you'd have more people talk about it.

as i have searched the site... which you should do, 'o2simulator' only returned 4 matches.. one of which is this very thread.

The o2 sensor in all OBDII vehicles have only two modes closed loop and open loop. Its not hard when you think about how many volts it produces when the car is cold untill it warms up. It just seems more practical to use something that simulates the voltage of a heated o2 sensor. I already tried the 5 buck fix it just doesnt work on every car ,I wish it would but it doesnt. Well anywho I think Im going to purchase one try it out and post whether it worked or not. Im confident that this will fix the MIL.

i'm thinking that you can probably make one of those for much, much less than $40..

parts probably would cost about $10-20

enjoy wasting $40. :P

You probably can make one but it comes in a weather pack seal like OEM connectors its all sealed up. Also what kind of parts how many hertz of Resistor would you need Diodes What gauge of wire would you need there are too many possibilities, also you can just wrap them in electrical tape and how do would you know with out testing it you might have to build a few before you get it right, knowing very well it might not even work. $40 is a little pricey im not going to lie. All I can say that it is worth a shot. If it works with an Aftermarket header it will definitely work with turbo applications also WELL KIDS IM DONE 4 2NITE WELL TALK ABOUT THIS MORE LATER, PEACE & GOOD NITE

If I was going to blow $40 on an o2 fixer... I would get the MMW CEL fix. that piece comes with their headers and it works.

I have tried at lease 20 diffrent anti-fouler setups none worked and also tried three o2 simulators that did not work. I have one cat and located my secondary o2 sensor behind this and never had an issue since.

Are you sure your 02 sensor isn't damaged causing the CEL?

ive had my anti fouler for 5k miles and no cel!
