Location of O2 sensor 1?

Hello all,

I’ve searched through quite a few threads, but I’m having difficulty finding the exact location of sensor 1 bank 1.

I have a 2014 Tacoma with a 6cyl. The dealership was less than helpful but was eager to fix the problem for $425 parts/labor. I would rather just do it myself.

A location and part number would be greatly appreciated.

Thanks in advance!

Brandon

 

Sensor 1 is the one closest to the engine (right downstream of the manifold and before the cat). Bank 1 is the side of the engine that contains cylinder #1, aka the passenger side

 

The O2 sensor might be hard to see looking from the right side of the truck it will be on the top of the exhaust pipe a little left of center then they do change things around.

It should be in that area .

 

Thanks all. I’ll see what I can come up with. Now I just need to find a part number to order a new one.
