2.7 Tacoma 2015 02 sensor problem

After buying (3)02 sensors from the dealer they can’t seem to find the right one for me. I need the right 02 sensor for bank 1 sensor 2.

 

Should be Denso 2344926 for auto 4x4

Sensor 2 is the one after the catyletic converter.

What code(s) are you getting that makes you think the sensor is bad?

 

I just bought that one. It’s the wrong one that sensor is for bank 1 sensor 1, the dealer gave me that one and the wire is way too long compared to the one in the back, 2344927 which is the shorter 02 sensor apparently (the one I needed supposedly) the code I got was p0037

 

Not according to everything I'm finding, Bank 1 Sensor 1 is 2349161 or 2349128 depending on production date.

Are you sure your looking at the right sensor on the truck?

 

This is what I have for Bank 1 Sensor 2
Not sure the difference, but there are 2 options......
Part number is BLUE

 

Looks like 89465-04480 replaced 89465-35650
That is if you believe ToyotaParts Deal......

 

I swear this should be something so simple but it’s been a pain I’ll say that. Lol

 

Are those 2 part #s from denso?

 

Yes, they are.
But they are for Bank 1 Sensor 1.

You say you need Sensor 2? correct?

If so, see my post above.

 

That's the Denso numbers both rock auto and oreileys show for the Upstream (Bank 1 Sensor 1), you said your looking for Bank 1 Sensor 2 which is the Downstream

 

Sorry the other person

 

Gotcha, well I went to the dealership today and took back #2344926 they said the new one should be in by Wednesday this week, I don’t have the part # for the one they ordered but when I get it I’ll let you know if it fits or doesn’t. Who would’ve thought there would be so many different part #s.

 

You aren't kidding.
What a pain in the ass to figure out.
But here it is right from Denso.

 

You would think they should be able to look it up by VIN and have the right one.

 

Okay, just got back from the dealer the right one was 89465-04520 the reason why they’re so many different part numbers is because of the different size driveshafts, the length of different exhaust systems and cab sizes on Tacomas.
