Sjackson2 Posted February 11, 2019 Share Posted February 11, 2019 Anything else that could cause both upstream o2 sensors to suddenly throw codes for no activity? Seems weird theyd both go out at the same time Link to comment Share on other sites More sharing options...

Seems weird theyd both go out at the same time I've had both my downstream 02 sensors go out at the same time, I've also seen other vehicles where their 02 sensors would go out in pairs.

DirtyRhino Posted February 13, 2019 Share Posted February 13, 2019 This is interesting, I’m curious to see everyone’s input, I’ve been getting codes for all 4 of my sensors at any giving time it changes which one it wants to throw codes for. It originally was only bank 1 sensor 2 and I replaced it. Now I’m randomly getting codes for all 4. Not always the same ones either. It’s driving me freaking nuts.

Sounds like it might be if it’s intermittent Link to comment Share on other sites More sharing options...

DirtyRhino Posted February 15, 2019 Share Posted February 15, 2019 Are you kidding me smh, I’m literally kicking myself in the ass for not figuring this out sooner...is Nissan still making these sub harnesses or people making their own harnessSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Sjackson2 Posted February 15, 2019 Author Share Posted February 15, 2019 dont buy it from nissan. its over 100 bucks. make one out of two pieces of good quality cable and attach your own eyelets.My vehicle actually doesnt qualify for this tsb....and i dont have the bolts in the same place on the manifold as yours does...but i just made myself a bracket and attached the two grounds to it that go to the harness that the o2 sensors are on. I then attached on more cable and ran that back to my negative battery cable and it fixed the bank 1 and 2 no sensor activity codes i was getting 1 Link to comment Share on other sites More sharing options...
