You can get the denso sensors from Rockauto. Make sure you get the right model year. Their price on these are way closer to reasonable.

 

I purchased all four this summer. I just checked Rock Auto and they are still available.

 

Also, Denso has sold what they call "universal" parts, which are the exact same sensor but with a longer wire harness pigtail so that it can be used an a number of different vehicles. You zip tie the excess wire out of the way.

Because it is far easier for them to stock these which cover dozens of models the price is discounted.

I wonder if the Denso site is only saying they don't sell the exact ones any more (with the perfect length wire), now that the FJ is 10 years out of production? Luckily the sensor won't care if it has a few inches of extra wire.

I am looking to replace my AF ratio sensors and it seems DENSO is no longer offering them (according to their website)

What 'Denso website' indicated that AFR sensors are no longer available?
What model year is your FJ?
densproducts.com is a major Denso distributor, and shows AFR sensors in stock ... around $175 for a AFR sensor for a '14 FJC.

DensoProducts.com

 

Denso website link is a no go for some reason.

 

That's odd ... I edited the post to go directly to the home page where you enter your vehicle details to search for applicable parts.

DensoProducts.com

 

You never mentioned what year you were looking for, but I just went to Densoautoparts.com and found them for an '08 (both OEM and universal):

The universal one is $80, the direct fit one is $97.

 

I bought all 4 Denso O2 sensors from Rock Auto. It was $350 for all 4 sensors.

 

Also note that the 'universal' sensors do not come with the required connector - just bare wire 'pigtails'.

If you go with these slightly less expensive sensors, you will need to splice on the connector from your old sensor, and the splice must be a very high quality, soldered and hermetically-sealed splice. Remember that the sensors are providing millivolt level output signals, so the slightest resistance in the splice, or a few microamps of leakage current between the leads from poor sealing can cause an inaccurate output signal.

I'd always go for the 'OEM identical' sensor, the slight cost differential is more than worth it.

 

The link works fine now, It must be on my end as I'm old and slow.

 

Sorry to revive an old thread here, but I'm trying to order a set of 4 myself from Rock Auto and wan t to make sure I'm looking at the right parts.

I see the two downstream ones from Denso are designated as left/right, but I only see one for upstream.
Do I need to just order two of the upstream ones, or am I missing something?

 

Correct, one each of the left/right sensors, and two of the others. Also, some people have had issues with counterfeits on RockAuto, so I'd recommend https://www.densoproducts.com/

 

The same upstream sensor is used for both cylinder banks.

 

Would you please share the part number for the upstream Denso sensor? I do not see them on the site. Thank you.

 

Odd - currently neither densoproducts.com or densoautoparts.com (Denso USA corporate website) are showing A-F sensors for the 2010 model year.

I sent in an inquiry, waiting for a response.
