Thread: HOW: Most OBD II: Remove the Rear O2 Sensor

oooook, thanx let us know when you find the right resistor, cos it's a mod i wouldn't mind doing!!!

hmm.. this is a thought. no problems with the b15. i did drive with it for a couple long drives as well. drove it for about 3 hours straight, and no light. made that trip 2x. how long of a trip are we talking vadium? i think your car is just a death trap original own doesnt change oil, you and your gas milage tests, faulting out both o2 sensors, etc.

Haha, I will say that the light used to not come up for about thousand miles. Now it's becoming more frequent...

Ok I found the capacitor, not resistor (my mistake), I will go to radio shack and pick on up

What values are you trying, at my work i have almost every resistor in 1/4 watt 1% and a nice selection of caps. I wouldnt mind trying some things if you have more than one theory. Let me know.

The only other thing that I have in mind is this write up

This Capacitor:


I'm not 100% sure if if i need a new capacitor or a different resistor, the resistor i used is 1/4 watt, while the one the guy used is 1/2 watt... itnersting.

mmm seems like i'ts one of those things you'll have to try with every combination posible till you find the right one.... or just ask someone who knows electronics and helps you out! jajaja

I was reading in the FSM about this and i can do some experiments. I went to school for electronics so i am sure i can figure this out.

BTW your diagram is different than his. He shows cutting both sensor wires and putting the cap and resistor in parallel between the ground and O2 sensing wire.

Another thing is that my 95 O2 only has 3 wires so i have some figuring out to do. I will try some things and get back to you with the results.

Hahah, now that I think about it, I doubt its the capacitor, I think my resistor is just too weak!

I will get a new one and well see

So I haven't had time to switch out the resistors, but I moved the device inside, and the CEL hasn't popped up yet, so maybe it was getting wet hehe.

and mine just came back on. it must be because i drove through a heavy rain storm. thats the extent though. pulled the code and it said high voltage o2 sensor. erased it at work a couple days ago, and it hasnt come back since.
