Code p0340, where is the Camshaft position sensor located?

Just to let you know most of the time the sensor will not fix this problem, this code appears when the timing chain, guide or camshaft position actuator, oil control valve is having an issue. Does the engine make a slight rattling sound when idling? If so, this can be the problem, if you upload a short video of the engine idling, I can tell for sure.
