Hey my xtype jaguar 2.5l V6 petrol engine manual transmission AWD has been loosing power on the highway for a couple months. A scan was done with codes showing P 0037,P 1647 and P 1646.The technician says I need 2 new 02 sensors. Can someone tell me which sensors to buy I find the different banks and right vs left and upstream vs downstream to be really confusing. I would appreciate the part no of the sensors needed.
Thanks

 

The oxygen sensors are VIN-specific. Here is a link to the page on SNG Barratt's website showing the available parts for the 2.5 litre petrol exhaust system:

The Technician should also check for clogged catalysts.
