Oyxgen Sensor - Again
Where is the oxygen sensor bank 2, sensor 1? I have the DIYdata book for my 07 LS46 but can't figure out exactly where the sensor it is or how to change it. Any help would be appreciated.

I'm not sure how helpful this is... someone posted they could see my o2 sensor in my photos on this thread. Hope it helps.

I could not find images for the bank 2 sensor 1 but I marked locations for the bank 1 (1, 2) and bank 2 (2). Bank 2 will same location for the sensor but on the opposite side of the engine.

I read a post on this forum where someone just removed the battery tray and had easy access to the connector so you might want to look into that option. It's not a difficult job by any means but when your dealing with old and rusty bolts that can add another level to it.
Yes the floor is a bit scarred up from me working on it but it's holding up nice. I laid down the Epoxy myself.

It's really not a lot of work to get to the sensor compared to changing motor mounts. I have done my mounts and if you don't really need to change yours I would leave that job for another time. You just need to remove the bracket that the stabilizer bar bolt to on that side and remove the exhaust manifold heat shield. The bolts at the top of the heat shield are the most problematic because the alternator is in the way. You can get to them with various extensions, wobble sockets and ratcheting wrenches but it is a chore. Or you can just remove the alternator and you will have a clear view. The next thing is contorting your arm to reach the O2 sensor connector to unlock it. I could do it easy now since I know exactly what position I need to be in to get my hand up there but when your doing it for the first time you will be using a lot of choice words.

I replaced the Bank 1, #2 sensor a few months ago. Getting to the wire clip was impossible for me. I had to get somebody with a smaller arm and hands to do it for me. I was cussing the engineers out for putting it where they did. Thanks for the photos guys. Very helpful. I'm going to give this a shot this weekend (along with the front upper control arms!).
