Having fought a P0345 recently and P0349, may give extra insight. Per Ford hotline. Min oil psi hot has to be above 25 psi for the phaser to work properly. The code stands for circuit problem but base engine can also set code. The 5 blades that go past the cam sensor cannot be bent. If oil psi to the head is low it may sound like and exhaust noise on startup after 10 min sitting hot. 1 pin should have continuity to the other connector with both disconnected. The orange wire should have continuity to pin 44 in the rh -when facing pcm-connector.It cannot be shorted to the shield. After clearing the code it will reset after 2 restarts if fault is still present. A single coil on 1 of the 8 plugs can be causing a frequency problem setting the code. Disconnect 1 at a time and try restarting 2 times after each clearing of the code unless you have a scope to stress test the coils. If you have a miss or phaser noise fix the obvious 1st as the cmp will not cause the miss at and idle.
