P0150 - O2 Sensor Circuit Malfunction Bank 2 Sensor 1 Possible causes:
Faulty Front Heated Oxygen Sensor Bank 2
Front Heated Oxygen Sensor Bank 2 - harness is open or shorted
Front Heated Oxygen Sensor Bank 2 - faulty electrical connection
Fuel pressure not right
Faulty fuel injectors
Intake leaks
Exhaust leaks
codes 130 and 150 indicate a malfunction in the upstream oxygen sensor circuit which is affecting both oxygen sensors. This fault does not directly pinpoint the o2 sensors as defective, more diagnosis must be performed to get to the root of the problem. You could have a condition where power is not reaching the sensors, causing them to appear dead. There may be a fuel or airflow related issue causing the sensors to report abnormal readings.
To answer your question, the o2 sensors in question are between the engine and the cat convertor in the exhaust. Whether or not changing them blindly will fix your problem is another question.
Some time when you got new sensor s they have to be coded so the cry recognise them and some after market items aren't as good so try and get an oe part.
I assume you have cleared all the fault codes (eg. P0150 - P0167) and the Jaguar generic code (eg: P1000)?
Often the problem is that you know you have fitted the part - but the car's computers don't know and so they have to be 'told'.
Clearing the DTC codes is relatively easy with a decent Code Reader (EOBD CAN) but the Jaguar Generic code is sometimes not so easy as there is a road test sequence that often has to be performed before the 'Engine Light' (MIT) goes out permenantly.
A local MOT Garage often has a Code Reader gadjet and charges around a modest £30 to sort it.
