Oxygen Sensor M35 Nissan Stagea

[STAG123]

Hi Guys

I read a thread that some others with the older model stageas were just buying universal o2 sensors from supercheap or the likes and changing the plug has anyone had any luck doing this with the m35. I was quoted $180 for genuine nissan or $140 for a bosch just wanted to check what was the best option before i replace something im not even sure is not working.

cheers

I have a s/h one here you can have cheap...

Where are you located? I may be able to run a scan and test it's operation if you need.

[STAG123]

That would of been great unfortunetly I am at newcastle...

Do you know if its working? How old is it?

[scotty nm35]

No idea, it's off a spare motor I have here.

I have another off my engine somewhere, I know that one was working...

$140 for a bosch is good. They may have been a bosch unit genuine, just make sure it has the same plug on it as yours. Its amazing how much genuine stuff bosch made.

thread dig.

no one has any specifics yet for part numbers?

22690-AL600 - claimed OEM VQ25DET part. Amayama wants $433 for one.

everyone else uses EL falcon o2 sensor with no plug...

(from what I can tell) the plug is common as shit for Nissan's of the same era.

According to the NGK website, ADM VQ-equipped cars use a plug like this:

of which there are many sensors on ebay with that plug.

So I suspect the NGK part number VQ turbo engines would need is: OZA544-N8

(zirconia, 18mm thread)

Can anyone back this up?

[scotty nm35]

There are two plugs used on the VQ35, the front one you will need. The rear o2 has a blue plug and won't fit into the green plug.

The VQ25 and 30 run only the green one pictured above.

For less money you could buy a wideband and run the simulated narrowband output to the ecu.

[Leroy Peterson]

Yeah I ignored the post-cat sensors on the NA motors.

How do you change or simulate a narrowband from a wideband?

[scotty nm35]

Most units have a simulated narrowband output wire for this very reason.

Same pre-cat part number I quoted above. Thanks for the confirmation.
