P1647
Good Day from Allen, Texas.
I have a 2003 X-Type. My engine light came on, so attached the code reader, and came up with 1647. I understand that's a O2 sensor, bank 2. Where is this located? (some research tells me that's it on the driver's side of the engine, with access under the battery. I was looking for parts, and the question I have, is this upstream or downstream? That was a question that I did not know. Any advice would be greatly appreciated.
Thank You.

As you can see from the the excerpt below on the x-type banks 2 is closest to the radiator. The bank 2 O2 sensor fortunately is the easiest to replace. The connector is located underneath the battery.
I almost forgot before tossing out the O2 sensor replace fuses 38 and 42 they are for the O2 sensors. I can't recall which is for the bank 2. They can test good but replacing them will eliminate corrosion that might effect contact.
References to Bank-1 and Bank-2 are made with regard to the engine. When viewed from the flywheel the right-hand bank will be Bank-1
and the left-hand bank will be Bank-2.
