Possible locations per FSM:
-----------------
Remove camshaft position sensor (PHASE) (bank 1 and bank
2) from cylinder head back side.
-----------------
If necessary, remove intake valve timing control position sensor
(right and left bank) and camshaft position sensor (PHASE) from
intake valve timing control cover and front cover.
So you may have already found it since you see a lot of intake hoses. However, on the V6's, it's at the bottom of the motor and usually removed by removing two 10mm bolts while laying under the car. This was the case on the M35 I believe and definitely other VQ motors from Nissan (such as my previous Maxima's).
EDIT: Google images yielded these results...not sure what car they are for exactly but came back for M45 so look in these spots too. If one of them is correct, come back here and update your thread for the benefit of the community.
