anybody know or can find like the wiring scheme for the o2 sensor

theres 2 white wires, a black and a grey.

heres the deal:

i have a valuepackage civic(dx) and i upgraded to ex exhaust and header...well now its time for an inspection and i had to throw back on the ex downpipe and cat right?

well before on the dx the cat comes on the header and both o2 sensors plug into the header....one before and one after the cat...well with the ex i had lengthen the o2 sensor to get to the cat. well somethings wrong, and it could be in the wiring i did so i wanted to see which each wire is and where i went wrong...im not buying a new o2 sensor and i wanna get my inspection done

please help. im trying to search at the same time.

 

would this really work?

nope it wouldnt.


I dont really know these new 3-4 wire 02 sensors, the only EF's were so nice to only come with a 1 wire o2.

 

Sorry this is off topic and is not going to help your problem but i'm converting to an ex exhaust as well and I was wondering what wire gauge you used?

 

for what? to extend it?

14 guage. duno if that was a mistake or not.

 

as long as you matched the wires up correctly ground to ground and positive to positive you sould be OK as far as the wiring is concerned. Did you use the DX sensor or the EX??

 

the dx sensor...but i fixed it and now my CEL is off and i can get my inspection done and get my hi flow cat back on yaaay.

haha.


oh and i got a digital camera so i can get pics of my mugen lip 2mrw after i wash my car

Hurry up already dude!

 

gonna paint that lip?

 

eventually.

we'll see. it looks pretty good how it is. maybe a more glossy black or something or a gunmetal color

 

oh ok.

 

Just to answer the question....the o2 sensors are all theoretically the same from car to car.

They are four wire sensors, one is a heater wire, one is a sensor ground (almost always green/yellow), one is a heater ground and one is a signal wire. Colors vary b/w primary and secondary but I have scanned ecu pinouts on http://www.7thgencivic.com, my username is the same.
