PO345&349 Codes
I have searched and read so many things on this, I have double/triple checked all wiring and all cylinders on bank 2, codes are for cam position sensor intremitent or no signal.
I have just replaced all timing components including phasers, tensioners, chains and guides. Note to anyone doing that job! Use locktite, I had a guide bolt back out and break the staionary guide. I said if I am in here everything is getting replaced again. With that said I am getting the 345 and 349 codes now, usually after a couple of start ups. the truck seems to be running great is the kicker. I didnt use the chain marks but marked my heads and phasers and keep reading a tooth off would be compensated by the computer.
I have swapped the sensors and same comes back after a while, any input appeciated. Have not swapped the VCT solenoids yet but not real sure if they would cause this I have read yes and no.
Sorry about leaving out, 2005 f-150 lariat, 4x4, auto, 5.4l
thought i had put in a sig.

Come on guys someone has to have some good input here, runs great and ran all the way to work no problem the when I started for the second time it came on, that seems to be the trigger starting the second or third time, if I just drive its fine no codes. Starter and charging system seem fine.

Yeah I need to know too. Got the exact same issue. Changed out driver side cam phaser. Now I got the same p0345 and p0349 codes. Truck runs and idles fine. CPS connector and wiring to PCM checked out fine. Only thing I haven't checked is the crankshaft position sensor. But I'm also wondering if it could be the dorman phaser vs using ford part phaser.

Mine was out of time not sure how I messes that one up. I have replaced been into mine 3 times. Not phasers but the plastic chain guides. 1 time I didn't use locktite and a bolt backed.out pretty sure my oil pressure is low. Fixing.to replace the motor. New guys out with along block for $2500.00 40,000 4 year. Not.a.bad deal

So yours was out of time to cause the p0345 and p0349 codes?
I marked everything so not sure how mine can be out of time.
I haven't replaced the crankshaft position sensor yet. Heard that could cause those codes too
