Default Where are the O2 sensors?
I am getting a P0038 code. Bank 1 sensor 2. I am getting conflicting information as to which of the Jeep bank 1 is.

The larger problem is I am not seeing any sensors at all. Probably looking in the wrong place, but a Google search says Sensor 2 is behind the CAT, but I don't see any sensors in the exhaust system.

I think my Jeep info shows, but just in case, it is a 2015 JK Unlimited Rubicon.

Bank 1 is the passenger side. As for the location of the sensor, this video will be similar for you.

Well, that explains why I couldn't see them. They are behind the inner fender..

Thanks!
