O2 Sensors
The connector for Sensor 2 Bank 2 is located at the front of the car just below and to the front of the battery. It is difficult to access and the best way to do so is to remove the battery and tray assy (Remember you will lose your radio information so you will need the unlock code when you replace the battery).
Sensor 2 Bank 2 is the Black connector, to remove the sensor release the connector and sperate from the plug. The sensor can be accessed from under the car and you will need a 22mm open ended spanner to remove it, special tools are not required fro this sensor.
The connector for Sensor 2 Bank 1 is located toward the rear of the engine bay on the bulkhead. It is fairly easy to access.
Sensor 2 Bank 1 is the Black connector, to remove the sensor release the connector and sperate from the plug. The sensor can be accessed from the drivers side but is fairly tight to get your arm in you can not access from under the car. You will need a special tool 22mm socket 50mm deep with a slot down it.
The sensors heater can be checked fairly easily if you have a multi meter that can be used to measure continuity (an ohms setting) measure across the two black leads, normally the silver terminals in the connector. The value should be 5 ohms or less, a nominal value is 2.5 ohm. This would indicate a good heater, anything above 5 ohm would indicate an open circuit. Conversely below 1.5 ohm indicates a short circuit and a faulty heater.
The Jaguar part number for these sensors are 02C2S38497 at the time of writing this I have been unable to locate a generic equivalent in the UK
