I accidently ripped my o2 sensor wires (4 wire) and if i solder it back together will i still be able to pass smog? one of my shop teacher says that extending the o2 is illegal so I really don't know if it'll pass smog. and also is it a good idea to get a new one? i was thinking about NTK's o2 sensor, would that one pass smog? thanks for ur future help!

 

yes it will pass smog....i had to cut and extend my 4wire 02 so that it would plug into my harness...i passed smog and have no problems watsoever

 

thanks man

 

so what about them ntk o2 sensors? are they worth it?

 

what gauge is the o2 sensor wires? i need to extend mine to fit my header on.

 

i'm not too sure abuot that hopefully somebody knows

 

bump

 

if your going to extend the wires, go with a thicker gauge wire ( lower number gauge) because the resistance grows with an extended wire. The o2 wires are 18 gauge I believe.

My check engine light came on occasionally telling me that the o2 input was slow. It hasn't come back since I resoldered thicker wires on there. I used a 12 gauge because that was the only one I already had.

 

ok cool thanks

 

there are two black wires on the o2 sensor, if i'm soldering the wires on does it matter which black wire goes to which?

 

I'd imagine that it would matter. I just looked at a wiring diagram and each wire goes through a different path. so in short, yes it does matter. gl
