Where is the o2 sensor?

[jmolina]

header downpipe

[tweezy]

no the actual wire not the insert hole

Follow the lead from the O2 sensor...

[tweezy]

what happen was i just got my headers installed from a shop and im assuming the guy forgot to put the o2 sensor back so i was trying to find out where it can possibly be so i can replug it but i cant find it.

[jmolina]

it has to be over that insert hole, might just be tangled up in there, green and black wires not sure.

[tweezy]

you think it could have fallen off?

[noobcake]

no
is your o2 sensor even in the downpipe.

[jmolina]

i don't think so, its held by two wires, if it has fallen off, look for the 2 wires and buy a new one, maybe the one who installed your headers ripped it off, and did not tell you

[jmolina]

is your o2 sensor even in the downpipe.

he said its not on the downpipe

Oh... that's why I don't trust most shops.

If I remember correctly, the O2's plug should be near the front of the car, to the right of the battery. If I had an engine bay pic I could point it out for ya...

Ninja edit:
What brand of header did they install? Some aftermarket headers have the O2 sensor installed down lower, practically under the vehicle.

Umm... what?!

My O2 sensor plugs in around the area I highlighted (can't find an exact picture)...

sorry buddy ,no O2 sensor there

[deevergote]

Phil, he didn't circle the sensor... he circled where it plugs in on the harness.


It depends on the header that was installed. Stock, the o2 sensor on the F22A1 is in a different position than the sensor on the F22A6 (I forget where the F22A4 sensor is... I think in the same place as the F22A6, but I'm not positive... someone will provide that info).

Since the header is aftermarket, we need to know what we're looking at. Some header manufacturers, knowing that the CB7 has two different sensor locations, put TWO bungs on the header. One is used, one is plugged. I believe Megan Racing does this. Others sell headers made for a specific engine, with the bung in the same location as the stock bung.

Now, unless you already have an o2 sensor plugged into one bung, and the guy that put your header on didn't bother plugging the other one... there is only one thing that I can think of... he cut the wires and disposed of the o2 sensor completely. If that is the case... he damaged your car. You need that.




Take pictures of what you have. Get a top shot like the one frootloops provided, and get one from underneath, showing your downpipe. That way, we'll know what you're looking at, and we can help much better.
