Hi CL

Need some help here, im trying to save some money and do my O2 sensor myself. From Swell with the CL discount its going to be 155.31 but I see on Rockauto that Denso are much cheaper. Now Rockauto has the part description as upstream/downstream cyl 123 and 456 so on so on. So what is the correct part to order for O2 sensor (BANK 1 SENSOR 2)?

I believe it is DENSO Part # 2344626 Downstream; Cylinder 1, 2, 3. Can some one confirm that and if some one as ordered the same part give there feed back on it?

Also I've read that that some people have had to cut the connectors off some of the aftermarket the O2 sensors and solder it to the original connectors or something like that I would like to avoid this altogether. juz want a plug n play

Thanks in advance

 

I got all 4 of my sensors (GS430) off of ebay for less than $250... it's also worth into looking there if you can find the correct part numbers and seller. Unfortunately, can't help you out with the part #.

 

Just ask swell for the part# and price and u well get back with them

 

After a little deeper research (I should kick myself) Links to most DIYs for the GS sticky someone had the same O2 sensor problem and it was a sticky.

But then again I already knew the CEL code and where the O2 sensor was located so I didn't think to look there, and sure enough it had the right Denso part #

the correct Denso part numbers are:

(1,2,3 precat) Bank 1 Sensor 1: 234-4048

(1,2,3 postcat) Bank 1 Sensor 2: 234-4626

(4,5,6 precat) Bank 2 Sensor 1: 234-4630

(4,5,6 postcat) Bank 2 Sensor 2: 234-4603

I was right (copied from Rockauto website) DENSO Part # 2344626 Downstream; Cylinder 1, 2, 3
Price: 54.79
That is a 100.52 savings off the ClubLexus price at Swell


Here is the Sticky if this thread helps anybody in the future:

Well after two days of driving without the CEL and feeling good, the CEL comes back on

Code PO430 came up so first going to attempted O2 sensor Bank 2 Sensor 2 using D.I.Y: https://www.clublexus.com/forums/per...placement.html

Just ordered the Denso Sensor from Rockauto 56 bucks

Heck I might as well order the other two sensors but it would still be cheaper than ordering one sensor from Swell
