My 96' is showing O2 sensor fault codes. I searched and found the following old post:

"Another Tip....for an oxygen sensor, ask for one for a 1991 Nissan Pathfinder and use butt connectors to connect the new sensor to the LR plug (the colors of the 3 wires match). Cost per sensor...about $25.00....." Paul - E-mail address unavailable...

Questions:
Does anyone have more info on these Nissan Sensors - part/model numbers? Will they work on my 96' 4.0L? Will the check engine light eventually go out after installing these - or only if they are LR ones? Will they thread into the existing holes or do I have to remove the whole exhaust and re-size them?
I'm just after a cheap alternative to buying the LR stuff, but if this route is going to prove to be too many headaches then I will bite the bullet and go thru Nathan Crabtree.

I was directed to this site :

http://www.rangerovers.net/rrpartsv.htm#exhaustnew

Nissan dealer for $90 (part number: 22690-85E10). Three out of the four wire colors even matched up.

I'm not sure what you're supposed to do with the fourth wire - just cut it off?

By Stephen on Saturday, June 23, 2001 - 07:04 pm: Edit

I guess for $90 for the Nissan ones, I might as well just get the originals from Nathan for the same price.


don't mind me - I'm just having a forum conversation by myself here.....

That part # corresponds with a 91-93 Pathfinder. Go to an auto parts store and get one for $20-25. Just take a look at the OEM one and compare wires to the new one before you walk out of the store.

By Stephen on Sunday, June 24, 2001 - 03:45 pm: Edit

Paul -
When you did this, was there just three wires on the Nissan ones that matched up correctly?
Were you able to get rid of your check engine light with the Nissan ones?

By Paul L on Monday, June 25, 2001 - 01:23 am: Edit

I just did some research on that part #. My 95 Disco doesn't seem to need an O2 sensor yet.........

By Stephen on Monday, June 25, 2001 - 11:09 am: Edit

I phoned a couple of auto parts stores and found that the O2 sensor for the 90'-92' pathfinder has only one wire on it. The mystery continues...

You are SOL. You need to get a gennie for this one. $90 from Nathan [email protected]

96 and up are 4 wire heated or some such crap.

If the car has less than 82500k miles on it doesn't Landrover have to flip the bill?

Wow, if I can get 82,500,000 miles out of my LR, I will foot the bill! ;-)

By Ron on Tuesday, June 26, 2001 - 03:59 am: Edit

O2 sensors are a "wear" item so no. Not even covered by warantee usually.

Good one Jeff.

Sorry, just saw the "k" tagged on the end and had to jump in there. I was still a little punchy this morning.

So is there any final verdict? Can the Nissan O2 sensors go in a Disco? ('98)

By Ron on Thursday, July 19, 2001 - 09:12 am: Edit

NO! 95 and 94 maybe 96 and up no.

You need to call and get them from Nathan for $90. Like i said above.

It's been suggested a Nissan PN 22690-85E10 will
work with OBD-II LR's. But, they're not that much
less then the ones Nathan sells.

Wow, $90.00 I was quoted something like $200.00 ON SALE!!!
Thanks for the info.

Have you checked into getting an NGK one? Part number for a 97 is 25017. Go to http://www.ngksparkplugs.com/apps/cars_trucks_suvs/ to find out if other years are different. A lot of dealers carry NGK and I would not be hesitant to own any of thier products.

Having installed this myself, I would have to say that it is SO MUCH EASIER to just get the genuine one from Nathan. It was a simple enough installation, but it would have been a major PIA if I was trying to fit non-genuine and if splicing had to happen. Access to a lift would make it much easier, but even then, it still would have sucked. The difference in the price between Nathan's sensor and the price of the Nissan one, plus the hassle of determining which one, getting one, assessing the situation under the car, making any necessary splices, and all the other frustration involved in using the non genuine one is pretty negligable if you think about it.

Another big caution: DO NOT USE IMPACT TOOLS OR AN EXCESSIVE AMOUNT OF FORCE IN INSTALLING THE O2 SENSOR. Use a gentle hand! The most common reason these sensors fail is due to a small platinum ring that will split if the sensors are installed too tightly, rendering the sensor useless.

I stole the following quote from alldatadiy.com. This is info from LR TSB #17/01/96/US, which has to do with the handling and diagnosis of o2 sensors. I think this may throw cold water all over the nissan o2 oxygen sensor idea...

"The most common sensor used (In other makes of vehicles)is zirconium based and generates a voltage of up to 1 volt based on the difference between the oxygen in the exhaust stream and that of the atmosphere.

Land Rover vehicles use a titania based sensor that operates differently. Instead of producing a voltage, the sensor changes resistance in response to oxygen in the exhaust. A rich mixture creates a low resistance in the sensor and vice versa.

A five volt reference signal is supplied to the sensor. In the case of a rich mixture, the low resistance in the sensor "pulls" the voltage low. Conversely, a lean (high oxygen content); mixture will cause the sensor to have high resistance and a high voltage. The typical range on a GEMS equipped vehicle is between less than 1 volt to more than 4 volts."

What I gather from all this is LR o2 sensors operate with a larger range of voltage than do other o2 sensors on other vehicles. Using a different o2 sensor will not supply over 1 volt - this will cause the engine to run rich because the ECM is looking for a signal between 4 volts but a other than LR sensor tops out at at 1volt. The ECM won't know its running rich, because as long as the sensor's heater circuit works and the sensor reaches the proper temp to take readings, and the ECM is able to operate in closed loop - it will assume everything is OK. Of course my assumptions may be off and are open for debate - but that is how I interperet it.

zirconium based vs titania. There is some good reading here:
