Pre and post cat lambda the same?

[Cro]

As above, I know that renault have them down as different part numbers but the likes of bosch have then as the same.

Is there technically / mechanically any difference between the two, could they be interchanged perhaps?

 

[Mark One]

I'd imagine they certinally are different.
Wouldnt mess with it if i were you. Get the multi meter out if your really curious.

I think they are the same bar the length of the wire.

I think they are the same bar the length of the wire.

yes, one is slightly shorter. I've swapped them to get someone out of trouble in a hurry before
