Had a quick look for you.
Theres three temp sensors, two just after the throttle bodies, and one in the Bank 2 inlet manifold.
Bank 2 is the passenger side of the car looking at the engine and your fault says sensor 2 on bank 2 so I would take a look at the G42 sensor that you can see on page 58 of the attachment.
If you go to page 376
of this you'll find instructions on how to remove said sensor.
Part number for the sensor is 079919501F and is around 45 quid without discount.
