Use a universal one their cheaper ,about 40 euros
Testimonial: "Really good info !!"
most sensors are 4 wires which i pay about 40 euros plus tax for,in the box they come in is a wiring code ,so you cut the wire and then look at the sheet and see what goes where ,now their are two white cables whitch are the heater feed and two other cables that must be connected the right way around so look at sheet and it tells you ,use a screw type block connector and away you go .easy job sensor is normally a 22mm spanner and the ones that pack up first are normally the ones after the cat .where to buy ?? auto factor

I have a 2003 Jaguar XJR which started showing the P1647 code. This translates to the upstream (before catalytic converter) driver side sensor. I talked with Bosch about using their universal 15730 sensor but was told that they do not have a universal sensor for the upstream position on this car and that the 15730 is for the downstream as shown on their web site under "position" on the compatibility search results. I ended up ordering a Bosch 15627 which is listed as a direct replacement and is working without issues.

downstream O2 code 1647. I tried a bosch 15730 universal but could not clear the code. The heater resistance of the Bosh is 3.3 Ohms. The denso 9G444AA, the part in place reads 5.8 Ohms, room tempreture. For inquiring minds the upstream sensors (gray connectors) read 1.2 Ohms for the Denso part. I don't know that this is the problem but this is the difference.
Take care with Universal Sensors they are not all truely universal. Thats why you are unlikely to find Jaguar listed by any of the manufacturers. I'm not saying that they won't work just have a chat with the supplier first. See:-http://www.bluejag.co.uk for more info on O2 sensors

Thank you! I found the correct Jaguar part no. which is CN2N3717 for any others searching but am interested in what you say about using a universal one. Can you give me a name, type or where to get one please
