I was doing some reading around on creating a D.I.Y. WBo2 for my turbo project. I found the information on http://www.diy-wb.com/02info.htm and I was wondering if the 5-wire sensor came as an OEM part on the 92-95 Civics. Can someone confirm this?

 

Mine's 4 wire.

 

Same here

 

The 5-wire sensor is a factory part for 92-95 VX hatchbacks. Not for all VTEC models.

Would that be the sensor?

 

the 92-95 VX, the 96-00 HX and the 02+ have wideband O2s. But it's not a real wideband, it's more of an in between type from a true wideband to a normal one.
yes, that's it.
Take note of the part number... 36531-P07-003 .....P07 = 92-95 VX.

 

$185... that's sweet... way to get busted in the ass on a part that needs to be replaced from time-to-time. It's parts like this that make me proud of my Mitsubishi. I've never paid more than $60 for an o2 sensor for it.

I was lucky that the donor car for my honda engine still had a good P06 4-wire (heated) o2 sensor in the manifold. My P05 D15B8 had a 1-wire o2 sensor. All I had to do was tap the engine harness in 3 places to add the wires that were missing, and a $2 plug from an accord in a junkyard to make it work with the P06 ECU.

 

Well, thanks for the input. I know nothing about a Honda what so ever. I'm just trying to figure out what sensor to use for my wideband setup.

 

for N/A tuning the VX Sensor should be ok. turbo applications not so much.
it really depends on where your target A/F ratio is.
But a true wideband is going to be more accurate.

if you're dyno tuning, the VX would be fine to get you close. Once you're on the dyno, who cares what the A/F is. more power produced is better no matter what the O2 says.

 

i'm helping tristan in his research, and i was just curious as to why this is not a true wideband sensor. does it not cover the same 10:1-19.9:1 band of a/f ratios as the bosch lsu4 wb sensor? you say it is not good for boosted applications...why is this? not disagreeing with you guys or anything, i just wanted a clearer answer. thanks...
