Where can this be found

Asked by for the 2004 Jaguar X-Type
the upstream sensor is before the cat converter,thusly the downstream sensor is after the cat converter,follow exhaust from exhaust manifold towards cat converter u will find sensor screws into exhaust pipe.
Hi, I appreciate your reply. I would like to know if it is a difficult repair, parts, etc??? Jaguar repairs are usually way out of line and I am taking it, I hope, to a small repair shop. I really needed to know, ahead of time, what I was getting into. Thanks so much, Elli
generally not difficult,but being a jag certainly more expensive than a domestic,for the part,just be sure the sensor is the problem,proper diagnostics are the key!!
