2011 370z secondary o2 sensor wiring schematic

SR_GUY · 12-14-2017, 10:06 PM

I need the wiring schematics for bank2 senosr 2. Unfortunately my plug fell off and shattered while I was driving. Trying to fix this but I dont know what wire goes to what. I've been looking everywhere for wire schematics for this and havent found anything. If anyone owns a 2011 370z and can take a pic of the plugs and wire colors that would work for me too.

If you do a search you should be able to find a link to the FSM which will have the answers you're looking for.

Yes, it does. You may have to dig a bit to find it but the info you are looking for (connector pin-outs, wire colors, etc) is there.

As SouthArk said, it's in there. Admittedly, it can be a pain in the a$$ to find some of that info but it's all in there.

It'll be in the Power Supply, Ground, and Circuit Elements. PDF for just that section is linked here

Did you happen to find the wiring schematics for the HO2Sensors?

I've just torn my exhaust system to bits and reassembled it with four new sensors and have tried everything else to resolve the P0051, P0031, etc codes that keep pestering me.

Thought that would do the trick for sure but nope.

Last thing to do that I've been dreading is tracing back the wires because there is no room to do it.

There's a fuse (or fuses, can't remember) for the O2 sensor heater circuits located in the fuse block by the battery. That's most likely your problem if it's just the 31 and 51 codes you're getting.

Went through the same thing a number of years ago where I replaced the sensors and still was getting the codes. Found and replaced the fuse and everything went back to normal.
