Changing O2 Sensor Bank 1 Sensor 1
Special Equipment and Tools Required:-
Jaguar X-Type petrol (all years) Part Number C2S51801
Standing facing the Flywheel end of the engine, Bank 1 is
located on the Right hand side of the engine, there are two
sensors one upstream, on the engine side of the catalytic
converter, and one down stream on the exhaust side of the
catalytic converter.
Bank 1 Sensor 1 is the Upstream sensor for this side of the
engine.
2.0L V6
Bank 1 sensor 1 is very difficult to access this sensor from under the vehicle, so the following description is based on accessing the sensor form above with the Inlet manifold removed, If your vehicle has in excess of 60K changing the spark plugs is also recomended to be done at the same time.
Changing the Sensor
It is always advisable to disconnect the vehicle
battery
before carrying out any work within the engine bay.
The connector for the sensor is found at the top of the fire
wall near the coolent expansion tank. It is the grey connector,
in order to release it there is a small clip on the top (or bottom)
of the connector that needs to be pressed as the connector is
gently pulled, disconnect this connector.

Bank 1 sensor 1 can just be seen from the top on the engine
bay if you look down toward the exhaust below the throttle linkage.
Shown here after the throttle linkage assembly has been removed.

Follow the instructions for the bank 1 spark plug change
Here
for details of how to remove the inlet manifold in order to
access the sensor. Release the sensor using the O2 sensor
removal tool.
Replacement of the sensor is the reverse process of removal.
There is no setting to be done, except to complete a
drive cycle with the vehicle, or reset the engine management
light.
