2014 - O2 Sensor replacement

Hey all,

I am going to be doing a fix on a CEL P0137 (Bank 1 Sensor 2) replacement this week, just trying to get a definitive answer on the location of the Bank 1 Sensor 2.

Originally I thought I read it was behind the passenger side wheel, then I saw someone say it's behind the "left side wheel".

Now I'm confused

I tried looking up the cylinder order so I could figure it out myself, but no luck. If anyone know for sure where the Bank 1 Sensor 2 is located it will be a huge help!.

Thanks

Update, it is indeed behind the driver's side tire for anyone needing this info.
What is your mileage? I think emission components have an extended period...
Around 60,000. I'v contacted Subaru and the Federal Extension covers ECM and Cats.

If the problem persist, I will see if maybe they can look at the cat, thanks for insight though!

Car problems always persist and only get worse... if in Calizuela, warranty is70000 mi.

I should have mentioned, I replaced the rear o2 sensor (so far so good). If the problem persists even after replacing the o2 I'll hit up Subie Service.

Thanks for the insight.
