Oxygen sensor signal wire

Does anyone know which of the 3 wires on the oxygen sensor (2 grey, 1 black) carries the signal I can tap into for an Air/fuel ratio gauge?

I have an annoying hesitation I'm trying to figure out, and just got the gauge in.

Also, the gauge taps into a narrow band sensor, which I think the joyner has. Am I correct, or do I have to get another O2 sensor?

Thanks to any who reply!!!

Do you have the computer wiring schematic? It can be downloaded from http://www.utvboard.com/topic/392-parts-pieces-and-information-for-our-troopers-joyners/ It's at the very end of the post.

According to the schematic, the one heavier wire is the 14 volt feed wire and the other two go to the computer. You could unplug the connector and measure the supply side voltage on each pin or measure the resistance to ground of the sensor side, the one with a resistance will be power, the two with out resistance to ground will be you sensor.

Joyners are narrow band. A narrow band sensor doesn't tell you much. It only senses rather it is too rich or too lean but not by how much. I don't think I would waste my time on the narrow band.

So does that mean that it doesn't matter which of the two I connect to?

The A/F guage does say to connect to narrow band, but I can understand what you mean. If it doesn't work well, I can always pull the last O2 sensor and install a wide band one. There is a thread on replacement O2 sensors somewhere here...

All connected to the second 02 sensor.

Funny thing happens - the first minute or two I'm reading lean, as in 16/1 pretty much through the whole rev band, then my readings go all screwy - from 11/1 to 20/1. Sometimes I get confirmation by how the T2 runs, but sometimes not. Any ideas?

You need to be on the first sensor, not the second. Don't know if this will help what your getting but you will get incorrect values from the second sensor. The second sensor is after the catalytic converter and the catalytic converter alters the values of the fuel and oxygen. You need to be looking at the gases comming directly from the engine, so start there.

      Which is the best oil to use ?
      By Prepper
      I have been doing a little research on which engine oil is best for UTV engines.  There seems to be some disagreement over using a good quality regular engine oil, and the necessity of using "M2" (or wet clutch suitable) oil.  My understanding is the "wet clutch" suitable oil has less friction reduction properties (hence a more responsive clutch with less slippage).  While less friction reduction properties would seem to be better for the wet clutch... it would not be best for the internal engine parts like camshaft bearings and other moving parts where friction is detrimental and would lead to premature failure.  Some folks swear you need M2 oil, while others say they have been using regular motor oil for years and their clutch is just fine.  Could they both be right ???
      Any thoughts ?

      Kubota RTV-XG850 Sidekick shifting into nuetral problems
      By Paul L
      When I am driving at 30 to 40 mph on the highway, the display will change from H (high) to R (reverse).  It does not actually shift into reverse, it seems to shift into neutral and starts losing speed and the gas pedal has no effect.  After the rpm/speed drops for 5 seconds or so, it changes back to H and runs fine for another minute or so.  You have to try to drive it at less than 5000 rpm or so, to try and keep this from happening.  Any ideas on what the problem might be?  It only happens at the higher speeds.

      Black O2 Sensor?
      By Homeowner A
      I've been having misfire issues with my UTV 400 when it gets warm and I've thrown all kinds of parts at it so far with no permanent resolution.  Today I removed the O2 sensor and it is black on the end.  To me that means it's running rich and/or the sensor isn't working.  I replaced the sensor with a new one and will see how it goes I guess.  With EFI, I'm wondering why the sensor would be this way with low hours and mileage?  Is there a way to adjust or lean out fueling on these?  Thanks in advance.

      Can’t figure out what part I’m missing
      By Grant
      I recently bought an axis 500 and it’s missing a box or something the plug is L shaped I’ve looked through the wiring diagrams and still can’t figure it out. The plug is located right near the battery housing

      Predator 670 manual oil pressure gauge
      By Jim Kessell
      Hi All
      Just installed a predator 670 on my Landmaster. My question is can I remove the low oil pressure wire fitting and plumb my mechanical gauge into that access point?
      Thanks in advance for your advice !!
      Jim
