I think you will still pass, since your car is an 02. They use ob2 tests on cars that are 95 and newer.

Sorry, but I honestly have no idea what emission restrictions are like in NY... do a search, i bet you will find numerous threads about passing smog inspections.

Looks like a good write-up. Just a quick question...is this overkill? I am new to Subie's, but on my VW with catless DP, we would just neatly zip-tie the 2nd (post-cat) o2 outside of the exhaust track. The OBD2 scan would read the sensor as there, and it would just read outside (clean) air. I think this would be the easiest and cheapest way to avoid a CEL. So is the issue that this would get caught in inspection? Haven't had those in a while but I don't remember them getting under the car.

Not sure, i'd have to do a little more research, but i remember reading some things when i was originally researching this topic for use in my WRX and i found that a couple of times i saw that articles said not to completely pull the sensor out of the downpipe.

The reasons were as follows:
1. To keep from being exposed to the elements
2. To keep it in a very secured position (screwed into the downpipe itself is a little more secure than strapped to the crossmember with zipties... not that there is anything wrong with that)
3. To pass visual inspection in certain states/counties for passing smog. I remember reading that certain states/counties will make you pass visual inspection of catalytic converters and o2 sensors.

Bottom line, there are many ways of doing this fix, including the one you suggested, and i'm not going to say that mine is better, just that it works perfectly for my (as well as many others) purposes.

If anyone comes across this and has any other reasons why this fix might be more beneficial than another route... please post it!

Thanks!

Installed the anti fouler on my rear O2 sensor on 6/25 and cleared the code and drove it for 2 days (103 miles) and got it inspected on 6/27 and it PASSED! Its still off (knock on wood) However when I did put it on be VERY careful of the wires attached to the O2 Sensor since they become stretched when it is in.

I still get a CEL with this but it only pops up every once in a while and then goes away again a few days later.

Hey all,

I haven't revisited my thread in quite a while! Well, it would appear that there are some mixed results here. Not sure why that is. All I can say is follow the directions exactly as they are written. Don't cut corners, each step is there for a reason (not to imply that any of you who have been unsuccessful have cut corners, just a general suggestion to all). At first when I did this i had a lot of trouble getting the resistor to stick/stay in contact in the socket. Try fiddling with that and it might resolve your problem.

I've actually gone back to complete stock exhaust. I couldn't really justify throwing so many more emissions into our atmosphere for an increase in power. With everything stock it's a really fun car, and that's good enough for me

Good luck to everyone.

anybody with an 04+ car shouldnt use this 'trick' as the rear o2 sensor is used by the ecu on these cars to adjust fuel trims and if you **** with that...it is bad juju

it is far easier to use a tactrix cable or have a tuner turn that code off and retain the o2 sensor function
