On a Ghibli S.
I know there are four over two exhaust systems. One pre-cat and one post-cat.
Can anyone tell me which are which please ?
We have sensor 1 & sensor 2.
We have bank 1 & bank 2.
Which is drivers side and which is passenger's; which is before the cat and which is after.

Thanks in advance.
Ian.

Which year? I'd have a look at Autodoc, they give cross references to other vehicles which use the same sensor.

For example, for the pre-cat sensor for 2017-

OEM reference number(s) comparable with the original spare part number
  • C2D 24756 — JAGUAR
  • DX23-9F472-BB — FORD
  • DX23-9F472-BC — FORD
  • LR091881 — LAND ROVER

Thanks for that Zep.
However, I'm still trying to bottom this out.
I've discovered that the banks 1 & 2 are left & right (but which is which ?)
And sensors 1 & 2 are pre & post cat (again which .....etc ... ?)

Well, left and right are normally when sat in the car. And 1 and 2 are normally 1 = pre-cat and 2 = post-cat.

The AUTODOC site is useful for figuring out this stuff, but I imagine the left and right are the same, only pre and post will vary.

Hi.
I get that the left & right are as you're sat in the car, but which is bank 1, left or right ?
