Just a quick question. The secondary O2 I have for my Hytech is throwing a code 67. I still have my original O2. What would be my options if i wanted to extend that original one. I have heard somepeople say something about the DC spoerts extension, and some others just say use shielded wire to extend the harness. What do you guys think would be the best an easiest way of going about doing this??

If worst comes to worst, I may try and buy a used one thats already extended.

TIA

 

dont buy a used o2! you can extend the wires just solder( how ever you spell it) the wires! how long do you need it? i have brand new o2 sensors with long wires on em let me know ill give you a deal on em!!

 

I need one about 8 -10 inches longer I would think. If I just splice the wires and solder them in, is there any special type of wire I should be using to keep the same resistance in the wires?

Let me know about the ones you have though anyways

 

anyone else??

 

go to an electronics shop (not radio shack) and get shielded wire. I forget the name, but they should have one that's especially strong for automotive/industrial use. j00 don't want those wires picking up interference or else it'll throw off the voltage reading to the ecu.

That's not necessary.
Looking at the wiring from the O2 to the plug, it's actually a silver wire (probably tinned copper for durability), and then it goes to a standard copper wire in the harness. There is no shielding on these wires, except for heat shielding.

You'll find that this wire is very hard to solder. I had great luck actually twisting the wires together and heat shrinking the hell out of it. Of course I now have some liquid flux which might work better.

 

Will the EX O2 Sensor extension harness not fit the secondary O2 plug?

If this is true and not much more costly, I wouldn't mind trying this. however, I wanna see all my options before cutting any wires.

 

I'd also like to know this seeing how I'll be recieving my SMSP within a few days =D

 

evening bump

 

.....a simple search for "o2 sensor extenders" in the archived topics is very revealing:

This one is even more helpful.

 

tried searching and didn't find that thread. Is that extension harness purchasable or a DIY job?
