Can anyone help with this code?

Hi, can anyone tell me where “camshaft sensor “B” circuit bank 2” is?

Is this at the front of the engine or back?

I have changed the camshaft sensor on the front of the engine for a brand new Subaru one so I am wondering if it could be the wiring? Or it might be the other sensor at the back of the engine (I have been told the have two camshaft sensors?) if the back sensor is “camshaft sensor “B” circuit 2” can anyone point me in the right direction to where it is on the engine?

Car is a 2004 Impreza STI UK spec

Thanks.
