Actually, that’s not the one you need to plug. You need to put the spacer in the o2 sensor on the midpipe UNDERNEATH the car. I’m assuming that you have an 02-03 car, which has 3 o2 sensors. If you plug the spacer into the one in the midpipe, your SES light should go off and stay that way. ---

Oh well! I’ve got some questions: 1. Why the heck would you need 3 o2 sensors? (I know one for MAF, one for cat-converter but the 3rd? you dont have 2 down pipes like a V6 or anything…) 2)Is the Ghetto Sim just a signal says the cat-converter is working? ---

1. I have no idea. Ask Nissan what the freakin’ deal was, they are the goofballs! 😃 2. The Ghetto-Sim just pulls the sensor out of the exhaust stream, making the sensor read as though the exhaust gas is cleaner than it really is. ---

There are only two sensors on the Spec-v’s. On the 04-06’s, the second sensor is on the midpipe while on the 02-03 it is on the exhaust manifold. ---

> [@PyreXXX](#): > > I’m assuming that you have an 02-03 car, which has 3 o2 sensors. Put down the crack pipe. :lol: There’s only 2 and they’re both on the exhaust manifold. I don’t know what everyone is bitching about SES lights for. When I had my header the #1 02 sensor was in the header and I relocated the #2 to behind the second cat on the mid-pipe. Ran like that with no ghetto sim, no nothing for a year and a half with NO SES lights. ---

You may have to “double stack” your secondary 02 sensor with another spacer (screw the spacer into the header, and screw another spacer into the spacer).:? Some people have had to do this before, maybe you’re one of those unlucky ones. Try it and see if it works. ---

maybe i should get one of you guys to look at it. i am not even sure if i have the room to put a second spacer on the O2 sensor before they connect with the fan housing… ---
