Anyone have any suggestions on where to find (1)O2 sensor? One of my friends managed to ruin the driver side o2 sensor unfortunately - I've already tried junkyards and I'd rather avoid the $140 other places want

Someone mentioned they thought I could use any 3 wire sensor but I've never heard this.

I did some research on the subject(british v8/land rover owners forum) and found a few different nissan o2 sensors that are suppose to be exactly the same(difference in price and plug).

Checked a few local parts stores and only one of the nissan sensors is stocked. Price $70(couldn't afford to drop the $400 LR wanted).. Only difference I can see is the plug and that the sensor sits more towards the center the center of the downpipe. Will this make an significant difference if I use it while having a stock o2 sensor on the opposite bank? The difference is a few centimeters at most - so I'm thinking its negligible.

Also whats the best way to actually tell if its working? i don't have the diagnostic box that some people run with the 14CUX - Can I just drive around for a bit and then pull the plug to check if its running too rich?

I'm going to change the plug and install it over my thanksgiving break - I'll let yall know how it goes.

Robert, check with the guys over at Megasquirt and perhaps Innovative Motorsports. That's very expensive even for a wideband O2 and if it's a narrow band it's flat out highway robbery. $20 would be more appropriate for a narrow band.

Robert, Chris Gill on MGExperience went through this. With the Rover ECU you have to use the Rover (or Nissan similar) to work .

Jim's right. I ended up finding a pair of used oxygen sensors and they seem to be working.

Take a look at this page about half way down. They have some ideas that might work for sensors

Here's another pertinent article about oxygen sensors...

Robert, oxygen sensor brands seem to have toggling voltage differences, I don't know why. Some vehicles don't seem to agree with a universal after-market brand; although they test good, it will not meet the vehicle's ECU requirement. Always check the OE manual for the proper 02 sensor specifications. Here's an excellent link on 02 sensors. [www.autodiagnosticsandpublishing.com]

When using an after-market brand on GM vehicles, I always had better luck with a Delco or Nippondenso. I know some guys (technicians) that will cut the plug off the end of a sensor that came from another brand vehicle and successfully rewire it for their vehicle; of course, they have perfect understanding of their work and own the proper test equipment.

Good luck,
