1 02 sensor? - B15sentra.net

02nismokiller · 11-05-2009, 05:56 PM

is it possible to only have 1 02sensor? i'm planning on clearing out my stock cat, and i bought the spark plug non-fouler's. when i go under to check where the second sensor is at, and there isnt any! the only one is on the header. if i were to clear the cat, will my SES light come on?
and my car is a 2002 spec v

sounds weird man. My 02 spec definitely has 2... You the second owner on this car?

You checked the header?!

You have an 02, which means one of the sensors is going to be above the cat on the header, and the second o2 will be below the cat, on the header as well.

If you still only have one sensor, which is unheard of lol, and you don't have an SES light already, you wont get one after the header install. That's for sure.

Make sure you only space the second. DO NOT do it to the first one.

http://forums.evolutionm.net/evo-how...cel-light.html i found this site, and the second 02 sensor is on the mid pipe. isnt it the same as on the spec v's? or are both sensors on the header?

02-03's have both o2 sensors on the header. 04-06's have the second o2 on the midpipe.
Maybe it was modified by one of the previous owners?

You don't need the second o2 sensor anyway so F it.

So you have an SES light?

Did you look where I told you? Because your second o2 sensor is not going to be on the mid pipe, especially if you don't see it there. Lol.

yea i saw it is on the header...thanks guys. and no i dont have a SES light on.

Lol, nice. Well yeah, make sure to use the anti fouler spacer once you clean out the header, On the 2nd sensor.
