Hi fellows

Has anyone changed oxygen sensors(pre-cat sensors) on GSV40?

I'm searching for the part number but can't find any.

Would love some help.

Thanks

Pretty sure I've saved more than one useful document you posted. Thanks

It looks like most parts are imported from USA.

I found this store based in QLD selling Denso products.

The seller confirms this part suits 2009 Aurion.

I will post a picture when the parts arrive.

I ordered a set of the pre-cat and post-cat sensors from an eBay seller located in Brisbane, QLD on 31st January and got delivery 1st February.

3 of these sensors were manufactured in Japan. As advertised, one of the post cat sensors was manufactured in the USA and branded DENSO First Fit.

I also located previously purchased pre-cat [air-fuel] sensors that were also branded DENSO First Fit. These were the ones that I fitted plus both of the post-cat sensors. 

The replaced sensors have been retained and will get a good clean, eventually.
