I am looking for the downstream 02 sensors of a 2003 2.5 x type v6? It is dual exhaust.

 

I've moved your question from General Tech Help section to X-Type section. Members here with the same model as you are most likely to be able to offer advice on the X-Type sensor location.

Bank 1 at the back near bulkhead
Bank 2 at the front by radiator

Upstream is in the manifolds
Downstream in the cats

 

Sorry dont want to sound special ed but when im under the car lifted from the front i see a long pipe that goes to the back and splits up into the two seperate exhaust ports. The pipe connects to manifold also. In short im kinda lost on what the cats look like and where after them are they. Any pics would help. Thanks

Thanks lol I took a bunch of pics so I will add em anyway. I am guessing 2 and 4 are downstream am I correct?

 

Yep :-)

 

Maybe help some others out.

 

How do change out sensor 2? Cant reach from bottom do I go in by taking out intake manifold?

 

What makes you think the O2 sensor is bad?...did you read a code or something?..I've not heard in all the problems that the X-type has, that the O2 sensors are ever a common problem or they are rarely a problem...Not saying you do not have a bad sensor(s)...but look into other things that give you bad O2 readings first.

 

I am getting codes P0420 AND P0430. I will change cats when I can afford to do so but I need to renew licences plates now. So just trying defouler trick and need to know how to get to o2 sensor 2.
