2007 infiniti g35 sedan 6 speed, car is throwing p0345 code, I have new cam sensor, even swapped bank 1 to bank 2 cam sensors still get code, new crank sensor, did engine flush oil was clean, slip light and vcd light stay on and seems car is stuck in limp mode, I can clear check engine light but others stay on. car sometimes will rev past 3500 but usually wont. on a cold start up engine sounds like a diesel truck but then sounds fine in a few minutes. also installed a new vct solenoid. I bought car from a friend really cheap cause he took it to the dealership and they said engine oil was dirty from lack of changes gummed up needed a new engine and I know that he took good car of it any ideas? on the notes from dealership it have clutch assembly for intake cam bank 2 can not be controlled leaving the valve wide open... here is a few videos
Have you consulted the FSM prior to posting?

P0340, P0345 CMP SENSOR (PHASE)
Description
INFOID:0000000000956646
The camshaft position sensor (PHASE) senses the retraction of
camshaft (INT) to identify a particular cylinder. The camshaft position sensor (PHASE) senses
the piston position.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor
(PHASE) provides various controls of engine parts instead, utilizing timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor changes.
ECM receives the signals as shown in the figure

The cylinder No. signal is not sent to ECM for
the first few seconds during engine cranking.
• The cylinder No. signal is not sent to ECM
during engine running.
• The cylinder No. signal is not in the normal
pattern during engine running
Something as simple as
