I got 2 new O2 sensors but I'm not sure which is left and which is right?!

They had different part numbers but they are not in the Nissan bags anymore :(

 

There's a Bosch part number on each and one has a green paint mark and the other has a yellow mark.

 

I would have thought they were the same thing on each side but there must be a difference.

 

How can I identify them?

not sure what would be different apart from possibly the length of the wire going to the loom??

As paul says they are identical.

IIRC the wire is also the same length.

That's what I thought when I ordered them as on stock they are different lengths but on delivery these are both the same.

 

There must be a difference as there's 2 part numbers for left and right and a different Bosch number on each :confused:

 

Sureley they are doing the same job though so why should they be different...?

Cheers peeps.

I'm sure you're right but just confused by the part number thing.

 

I'll just stick 'em in and see what happens.

The trim that goes up the winscreed (external) has two different part numbers for left and right however they are identical.

 

Just a nissan or Bosch thing I guess.

the only difference in them is the position of the fixing clip.

You usually get 2 the same size of O2 sensor when ordering from the US because 1 side is nearly twice as much at the other side and they are the same bar the wire length.
