Ive searched around didnt see anything. I bought some Obx headers for my 01 4cyl and i noticed that theres not a location for the o2 sensor on the headers towards the top. theres one after the flex pipe and then there the one near the top on the oem headers.

Anything i could do to make it work?

Thanks

 

you need to buy a O2 sensor extension, one from DC sports would work, you can buy it at optionsauto.com

or just use 4 pieces of wire for a buck fifthy

 

eh I didnt feel like splicing

 

so the plug for the o2 sensor on the top part of the headers near the head go's where? and connects to where?

Thanks for all replys

 

You'll have to have a 14mm(?) bung welded to the headers. I dont think the OBD2 system will work properly if you dont connect the first O2 sensor.

 

The header (not headers) already has a O2 sensor bung on it. It's just located further downstream than OEM. The second O2 sensor is in the cat.

As already mentioned, there are 2 very simple solutions: 1)buy an extension, or 2)lengthen the wires yourself. There is no welding necessary.

 

Yes but i thought the main 02 sensor collected measurements for fuel trim ect.

 

Yes, that's what the primary O2 sensor does. It just sits further downstream on the OBX header than it does on the OEM manifold. It's not going to affect the readings.
