bank 1 will be whichever side cylinder 1 of your engine is and bank 2 will be the opposite side. It's named bank 1 and bank 2 so that no matter how the engine is laid out, bank 1 is always on the same side as cylinder 1. I cannot say whether the right hand or the left hand one will be bank 1 as I do not know where your cylinder 1 is. The garage should know

you have a vacum leak either in a hose or a vacum cap, check all hoses and caps, replace questionable peices

SOURCE: I have a P0011 "Camshaft Position/Bank 1 code.

OK check the CMP sensor connector for cleanliness, sometimes oil can get in and disrupt the signal transmission to the ECU. Check the wire loom continuity all the way back from the CMP to the ECU. If the error code persists remove the cam sensor, clean its tip of any debris and refit.
