Are they considered a solenoid?
Maybe - seems almost like a "brake", a big coil, magnet, without a moving rod.
Like trailer brakes, even though those are just coils, electro-magnets, they're called solenoids.
Unlike the earlier 3.6, there's no oil involved, it's not a valve at all - the phasers are torque-driven, not oil or hydraulic.
I'd like to get my hands on one and test my theory.

They found damage to the passenger's side camshafts so they are replacing both cams, rocker arms, and followers or whatever they are called. They should finish today and I'll get it back Monday. I did hear pings but they were random and sounded more like knock. I don't know if ticking sounds people are experiencing are persistent or random. I had also asked them to carefully inspect the cams last time they had the valve cover off. I'm not sure why they found it this time and not last time.

Hopefully this is the final update...
They replaced the following and the problem is resolved:
What I had noticed was that it was down on torque. I heard random pinging that sounded like knock, and fuel economy was down.

Hey OP, I'm curious if this was a long term fix or if you've seen repeated issues? I am currently going through recent diagnostic issues with the dealer as well as a local shop after getting the same code.
With being a manual, I have to drop at least 2 gears to get the truck to pull itself along on flat when this happens, and its also intermittent. Of course when the dealer drives it they think it's miraculously fixed after an oil change...They thought dirty oil was the for sure cause the first time. The second time they've had it they now want to open up the valve cover (which I agree we need to see inside), but want $950 to take a peak, can't get gaskets to reassemble for at least 2 weeks, and can get me a loaner thein 4 weeks when they get one back.
This is ridiculous and beings I am at 87k, will all be out of pocket. The fact the VVT system is so problematic and yet another Pentastar with timing issues due to it are really making me want to return to another brand.
And @JeepCares , please respond to the message I sent last week looking for support on this issue.

My issue has been resolved. I've added another 5-10k miles since then. It's interesting that you bring up dirty oil. I am meticulous on maintenance and I went through a long stint where I felt I should have change the oil. I didn't have a record of it in my maintenance Excel sheet. I asked my 12 year old if he reset the oil indicator as he has a very bad habit of rolling through all kinds of settings and changing them for the fun of it. That has been extremely frustrating. I can't prove he lied, and I can't prove that I didn't change the oil and forget to log it. Normally I would write the date and miles on the filter, but these new filters don't allow for that. Worst case is I went somewhere between 1.1 and 2.0X times the interval while using Mobil 1. Now that I think about it, I drive a fairly consistent amount of miles per month. I should use the dates of my known changes to see if I went much longer.
Anyway, it hasn't happened again. If you are getting the same code that I had, and experiencing the same symptoms as well, then you likely have the same issue. Only open the bank that throws the code. No reason to check both. My dealer also said the valve cover gasket had to be replaced if they pulled the valve cover. I have not known of a VCG that wasn't reusable until it leaked. They are generally o-rings with funny shapes.

That is interesting and I was thinking the same thing on the O-ring style seals? I have zero faith in the S-Writer that was quoting me on this and was very unhappy with their communication, or lack there of. I was thinking the issue would be relating to what you experienced and fear the total out of pocket as I do not have any extended warranty. Weird that one would expect a vehicle to run for quite a bit more than 87k, what was I thinking??

Mine only made it 5x,000 miles, but I'd prefer that over 87k. Imagine the anxiety when I rolled over 60k.
I don't know if this has anything to do with it, but I changed my driving style after. I try not to run under 2,000 rpm. Often times before I'd have my foot on the floor rather than downshifting. Lame that a 1/2 ton with a V8 can get the same fuel economy as I can (~17 mpg).

They aren't allowed to use parts like that over again. If you've ever worked in a shop - you'd understand why. First time they try and a customer reports a leak - it's a come-back on the tech. They might get chewed on.
If it was MINE and I was doing it, yeah - maybe. But then these aren't your stripped down SBC either (and I'd never use a valve cover gasket over on a 1980s SBC or even MOPAR)
There are rules - and not using the same gasket over again is probably one of them - warranty or not.
You take something apart - it gets new seals and gaskets.
I can only imagine it's even more strict than when I did my stints.
Gotta ask - how many vehicles have you owned?

Not sure why this information is relevant. I own #2 and #5 of 5. I do all my own work except A/C and this (warranty work). I was in my first truck's engine several times and don't recall if I changed the valve cover gasket, but not every time for sure. It never leaked. The Ford's VCGs also have wiring harnesses in them. They damn sure don't get replaced unless necessary, and they don't leak. Every other oil port/orifice/seal/passageway does, however.
I'm not sure there is a 7.3L (leaker) out there that doesn't leak.I can understand this from a dealer's perspective. I can also understand that they would prefer the sell and the insurance policy. In this case it's a win/win for them, but I had to wait several days driving a different vehicle because of this stupid gasket. First they wanted permission from Mopar Jesus to remove the valve cover, then they had to wait for the gasket to arrive when they did receive their blessing. What kind of micromanagement is this that Mopar Jesus has to tell a dealer that they can or can't open up a valve cover?
These are all stories I was told anyway. I'm sure half of them weren't even true and were just delay tactics. I'm not sure if you even read the thread. I literally told them what to check for my first trip in. After 5 trips, two times in the engine, and two different techs one of whom started to repeat the steps the first one had already done, and a few months or so, it was finally resolved.
This is my first new vehicle, so it is my first experience with a warranty.

IIRC the OP said it was covered under warranty....

Thank you. There's a lot going on in this post and I must have skimmed over it. The symptoms OP had are identical to mine. I have an appointment in a couple of days to get a full diagnostic and am dreading it. Our last vehicle ('14 Ford Explorer Sport) had significant issues too. Two separate timing chain replacements as well as catastrophic engine failure that stemmed from poor design. At this point all I feel I can do is cry. It's disappointing. The brake pads on the Jeep have lasted longer than the engine has.
