My car is a Jaguar S-Type 3.0 petrol 2001 registered. Orange engine warning light on so had my engine checked out and it came up with code P0430 which is the catalyst system efficiency below threshold bank 2. The exhaust emission test showed excessive carbon monoxide at idle and after fast idle.
Question could this be the Lambda sensors? If so how difficult would it be to change these and where are they fitted?
Is there a diagram that I could view?
Any help on this subject would be appreciate.

Best advise I can give is take to professional. Test for code is long complicated and requires special equipment. Trying this yourself and just replace parts will cost $$$ and likely to not solve problem.
