I think it reads all its a nice scanned ihas 4.0 software
I'm not sure I have to look into it more, but I'm assuming it the vct. Stays in open loop because it can't detect the the cmp signal so it stays in full advanced Maby just a theory.

Repaired pcm connection, and no more funky readings on cmp bank 1 . But still have p0340/p0344. I think they must have screwed up the timing any ideas any one please let me know. When i bought this truck it just hard miss fire on cylinder 3 and a phaser knock , so they changed the phasers and all Hell broke loose. Thanks Jake

(I'm of the opinion that the P0340 is the code that is set if the PCM can't read the CMP sensor signal, and if the PCM detects a fault in the VCT solenoid it would set the P0010 or a P1380 code.)
(Those codes are for bank #1 and the corresponding codes for bank #2 would be P0345 for the CMP sensor and P0020 or P1385 for the VCT solenoid.)
BTW, the VCT solenoids should have an internal resistance of 5-14ohms and no continuity to ground.

no p0340/p0344 code aall the time
No it just sets The code for the vct.there is no code for the vct. the p0340/p0344 is all the time . If you clear the codes, they come back within four to five seconds of running, according to the freeze frame data.I also have a u1900 code, would that cause a p0340/p0344. I was told buy a ford dealership that could be spark plugs , cause it does seem to miss at 3500 rpm and again at 5000 rmp. What you guys think. Thanks Jake

The code for the CMP (Cam Position Sensor) circuit malfunction for bank # 1 is P0340 and the code for bank # 2 is P0345. (I don't see a P0344, so maybe my manual is not as up to date as your Genisis.)
The CMP sensor is in the front of the front cover while the CVT solenoid connector goes through the top of the valve cover.
The U1900 code is indicating that there is a fault on the CAN bus. The CAN bus is how the various modules communicate with the PCM and each other. (Modules like the DDM (Driver's Door Module), the ABS module, the Instrument CLuster Module, etc.) I don't believe it will effect your P0340/344.

Sorry about the typo, its is p0345 for bank 2 cmp. I'm gonna change the spark plugs to see if that helps, some techs say, if has a miss it can cause the code. And has a small miss at 3000 and at 5000 rmp. But i think its to do with the variable timing not working, and a fresh set of plugs never hurts. I said years ago I would never drive a ford again, and I'm fixing and repairing daily. 
p but its a nice truck so its worth the head ache. I think I'm gonna take it to ford . I want to get a power balance test done and have the scanner with the proper programs. I still think those guys who did the phasers, are off a tooth on bank 1 like what else could it be , I covered all electrical problems with that circuit. Please let me what you think thanks Jake

If your still getting the P0340/P0345, that says the PCM can't read the CMP (Cam Position ) sensor!
If the bank #1 cam was out of time you would get a P1381 if it was over advanced or a P1383 if it was over retarded.
That's what I'm thinking. If the PCM can't read the CMP sensors, it may not try to actuate the VCT solenoids and that is causing the engine to misfire. Or maybe the VCT solenoid is not responding to the PCM commands.
If you have access to a dual channel lab scope you can check the timing on bank #1's cam. Just scope the CKP and the bank #1 CMP signal. The CMP signal peak should line up with the CKP's 7th peak (after the missing tooth) while at idle if the cam is correctly timed.

Ok, with that U1900 code I also got B2268 and B1255, and I'm pretty sure those two are causing the U1900. One is for the steering wheel fault a.d one is A/C temp sensor or ambient out side temperature. Thanks jake. Still scraching my head on why I'm getting the codes p0340/p0344. It just don't make sense, got voltage , good connections , brand-new cmp sensors. And phaser replaced alternator. Good battery, supposidly the timineg is fine! . But the question is , if it got new phaser and the vct is not working ,why is it knocking at operating temp. I think i know why but not sure .please let me know what you think . And thanks for your help I appreciate all the help

Yes i agree, Im gonna get scope on that timing . And I agree about not being off a tooth, cause it doesn't show its over advanced or retard . There is not much i can't figure out but this code is a pain in the but . And I'm at limited data . I have no service manual to use at home . I just got ondemand5 at work and its not always helpful. Thank Jake

Yeah, if the phasers are not functioning, it might not be bleeding off some compression like it should, I am only guessing here - is this "knocking" you are referring to , is it like a spark knock?

more wiring problems
Yes its like a spark knock. But it doesn't miss. But I also may hay found another electrical problem , in the signal return wire, it says on Mitchell ondemand5 that at the pcm connector and the cmp connector on bank 1 , it should have a resistance greater than 10k ohums of resistance I don't, and once again wiggling the harness it jumps all around to almost nothing. Still repairing the screw ups . I believe they were not gental on the engine harness ,,, let me know what you think Jake
