Ok so I installed my Tsudo header and s-pipe yesterday and at the end I went to plug in the O2 sensors and the front was no problem but I can't get the one in the s-pipe in. Leads me to assume I should have put it in before putting it in. Anyhow I was wandering if I could just stick the O2 sensor somewhere under the car and secure it and then cap off the hole? If yes then what should I use to cap off the hole? As of right now with the O2 sensor out I have no check engine light and that is why I am wandering if I can just do without it. No matter what I need to cover that hole because it has a really annoying sound with it not sealed and a bad smell which I am assuming is comming from there...

 

Um... just "securing" the O2 sensor somewhere on the car and capping the whole will cause you nothing but problems.

Have you talked to the Tsudo people about fitting it in there? Like if it should be done before/during the install or after? Or does it just not fit in the hole at all?

 

What sort of problem?

 

Well, whether or not you have one now, I'm pretty sure you're eventually going to get a CEL since that sensor isn't reading anything properly. And if you're confusing your sensors like that, my understanding is that you're going to confuse the computer on other things too (air fuel mixture?). I don't know how true that actually is... that's just my logic. I just don't think I would EVER want to just kind of ignore the sensor and plug the hole. Just seems a bit half assed to me.

 

Anyone know what size the o2 sensor is? Like what size bolt would fit in there?
