I've just spent all weekend trying to get my 02 sensor off with no luck...

I've used the special socket and it's on that tight that it's just stripping back the thread.. Tried WD40 to loosen it and even with a breaker bar and a 22mm socket it still won't budge!

What are my options? :P

Replaced my O2 sensor with a nissan universal one from repco, worked ok for 1000km but then started bugging up. Was slightly hesitating at cruising speed then fuel economy went bad and finally engine light came on at cruising speed. My tuner said unplug the sensor and see if the problem is still there, so I did and that fixed it.

So now I'm going to have to replace it again. And this time it's going to be geniuine.

universal = :happy:

'93 HCR32 GTST OZA395-E2 $76.50ish from Bursons trade price, plug fits.

Just confirming for everyone, as this thread lacks R32 info. If a mod could add it to the first post in this thread it would be good.

I just had a look at mine this arvo quickly, been told the front one is playing up, but what did the stock RB26DETT come out with for R33? mine has o2 sensor at the rear with 3 wires, front one has only 2 wires coming from it?

which one has been changed previously? im guessing the one with 3 wires (i.e rear) has been replaced at some stage.

Now if going to buy one, are the front and rear ones the same on R33 gtr? or different part numbers?

on the R33 GTR, your o2 sensors should have 3 wires.

The one with 2 wires has been changed obviously to another type of sensor.

Front and rear are the same but with different connectors thus the different part numbers.

I replaced mine recently with a universal one from EL Falcon. Originally tried to solder wires but it's f**king impossible! It comes with a joiner though so i used that instead.

It's working pretty well, fuel economy is better (not sure by how much yet) but yeah see how long it lasts.

PS. Use anti-sieze on all exhaust bolts makes your like much easier getting them off later, thankfully whoever worked on my car did use it and it was piece of cake to get the old one out.

This is a good article on changing the O2 sensor on an R33 / R34 GTR. I've added it as a link to my GTaaargh O2 sensor page

If you find any part numbers that fit skylines or other useful links, let me know using the link at the bottom of my web page and I'll update the table. It saves trawling through 19 pages.

So the r32 rb20det and rb25det, came with two o2 sensors? one near the dump pipe? and one further down the exhaust, to quote the shop that tuned my car, they think my 02 sensor is lazy, so I suppose it's on the way out.

Hey guys,

I have apexi turbo timer with O2 sensor voltage reading feature. How do i know from voltage reading when my sensor are bad?

When i put the ign into ACC (engine isn't started yet), the display reads 0.2 V from O2 sensor. Is it normal? I have 3 inch cat exhaust on my RB20DET, I thought when engine is off, outside air would came inside and make the sensor reads rich near 1 V (a lot of oxygen). Any thoughts?

Thanks

Damn, this is a sticky? Was looking for a replacement O2 sensor for a RB25DE..got to page 12! total confusion.

Guys the O2 sensor only controls EFI in closed loop mode..cruise or light throttle, anything else is determined by your map values and if it's OEM then rich is the key word..to save warranty claims, aftermarket..you need a tune. Sooo your not going to see huge increases in economy, unless you do a lot of highway driving. This means turbo or non-turbo doesn't make a difference as far as the O2 sensor is concerned.

Also like MAP sensors or ECU temp sensors, they are specific to each manufacturers specs, even though they operate in the same range ie. 0-1v NB O2 sensors..0-5v MAP sensors..you need a replacement that duplicates the same specs...

BTW the lower sensor doesn't have anything to do with EFI, it monitors CAT integrity in a narrow band above 1200degF.

Thanks Kudos..going to place an order.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
