2018 pathfinder with dtc p0021 &P219F

2018 Nissan Pathfinder  3.5  L   SV   148 K .
with DTC: after timing chain replacement
P0021 Intake valve timing control bank 2
P219F Cylinder 4 air/fuel ratio

I replaced the timing chain and tensioner since they where making noise  . found the tensioner was maxed out and the chain was putting grooves in the timing cover.Seconder chains and tensioners where not worn.

 car has a rough idle only.. drives great . not sluggish at all. two days later both these codes showed up.
Oil is new . I changed it when I R/R the timing chain and tensioner.
I  removed the oil control solenoid valve on bank two and  provided power and ground . It function fine .

Not sure what kind of problem do I have mechanical  or electrical and where to start with the scanner.

I have had plenty of VVT solenoids that move when bench tested, but fail to operate the VVT system satisfactorily. I wouldn't rule out the solenoid just yet.
And obviously, if this code was not there before the timing repair, then there is the possibility of camshaft out of time.

Should I perform an ohms test on the solenoid? 6.2 ohms to 7.2 ohms should be good ? should I try and perform a crankshaft and camshaft correlation?

thanks for your help

If there is a crank/cam correlation scan tool.functionnfor that engine, then, yes. It likely should be carried out.
An ohms test will probably tell you less that the bench test. I would, if possible, swap the solenoid from the opposite bank and see if the code follows.
If it's not the solenoid, then you are probably going back in the engine, so from that stand point , it probably would be more cost effective to change it than opening up the engine again to check the timing.

Thanks again for all the help. I have scheduled the pathfinder for tomorrow. I will try the crank cam correlation and swap the solenoids. If this is no help , I will reschedule the pathfinder for next week and plan on taking the it apart again to correct the timing .
thanks again in advance . I will let u know what I find .

I'm pretty sure that these have an electronic motor setup for the intake cam and oil controlled on the exhaust. I am not aware of a cam/crank correlation option on the scan tool for these. What is the angle of the intake cam on b1 vs b2 if you look at the scan data? Are you fuel trims wonky bank to bank?

There is a bulletin for P219F that states if there are no driveability issues, to update the ecm.  I would personally focus on the timing dtc first though.  

Matt (Tutti57) is the Nissan Guru! Definitely pay attention to his advice.

thanks again Tutti 57 & Noah . I have scheduled the pathfinder for this Monday June23rd. I don"t thing there is a cam /crank correlation. I will let you know what the fuel trims and B1 vs B2 cam angles are.

Thanks again in advance

I added pictures

your right no crankshaft / cam shaft correlation.
Before I got started with the scanner data the only code that came back was:
P219F:cylinder 4 air/fuel /mixture ratio
I used the scanner and tried the following pids:
intake valve time assign angle 30
intake valve timing -B1 (degrees CA) 14.5
intake valve timing -B2 (degrees CA) 6.5
b2 degrees did not change

exhaust valve time assign angle
exhaust valve timing for B1 and b2 were the same.
I will get you degree numbers tomorrow.
Engine oil control solenoid on /off
commanded on and off with the KOEO
