I have this code coming up 5.4 lt can't find the problem. Replaced the sensor and checked the wires and found nothing. Also just replaced the timing chain tentioners and guides. Help.

 

Here is my guess
CMP (Camshaft Position Sensor)

 

Already did and no change.

 

My scanner says PO345 is CAM POSS CIR ER 2

PO349 is CAM POSS CIR INTER 2

 

Here is a TSB regarding the code your giving..

So you are saying that after I took apart the front of the engine and replaced the timing chain guides and tentioners that now the alternator is bad when before it was good? So if the alternator is bad it will send a signal to the bank 2 cam position sensor?

 

I dont write the TSB's I just read them......
