Have a 2001 XJ8 3.2 - love the car - trying to rectify fault - diagnostic code P1647 - can anyone give me the part numbers of the oxygen sensors and are they the same sensors used in the 4 litre model? Any help would be appreciated.

 

You can look up the part #s on either Amazon or the Denso O2 sensor sites.

 

Thanks for your help - will try that - much appreciated.

 

You are very welcome.

Check the boards for tips on removal and installation of the sensors.
It looks a bit daunting but removal of the rear plastic covers and LH manifold shield should reveal all.

 

Thanks for the assistance. Ordered oxygen sensors from Rockauto USA, paid 1/10th of the price wanted by Jaguar dealership. These sensors are Bosch part number BOS15626 (downstream) & BOS15627 (upstream). These sensors suit both 3.2 & 4L V8. Have fitted them, working beautifully.
