So I had a laundry list of CEL codes that came up
P0021
P0024
P0014
P0011
P0420
P0018
P0016
P000B
P000D

So after looking into it and going down the rabbit hole I switched the VVT solenoid around and it turns out I had 3/4 bad solenoids. Following what I have read on the forms and other sites I order 4/4 solenoids with new rings. If it goes away then it was all just bad VVT solenoids. Considering I was running 5W30 per turbo kit recommendation but also in very cold climate it seemed like that was going to be it. I install them and do an oil change clear the code and drive it around a little bit.
Then the codes come up
P0016
P219A

I check the wiring to see if I can find heat damage or breakage and I don't see anything. I drive it around again and the code changes to just P0011
I can switch the vvts around again but this time they are all brand new.

Or should I take the full engine harness out and go through it more thoroughly ? Is it possible to get a cam position reading without a subaru dealership level scan tool ? Or is my best bet after checking the harness to manually reset the timing ? From what I read that some people have replaced harness/engines and it is an issue. Some even replace the ECU and its still a problem.

Now its a turbo kit that sits by the battery/firewall but I have pretty good heat shielding around all the wiring, the up pipe/down pipe, turbo blanket, the battery, wiring going to fused box, wiring going to high pressure injector controller and starter. I even have some extra heat shielding on that as well.
