Hey all, I'm having some engine codes after doing the following work:
Valve Cover Gasket
Spark Plugs
CCV System
Oil Filter Housing Gasket
Throttle Body Gasket
Fuel Filter (w/new hoses and clips)
Cleaned ICV
Cleaned Throttle Body
I was originally just going to do the valve cover gasket, plugs, and oil filter housing gasket, when I snapped the crankcase breather valve trying to get it out of the way to remove the valve cover. Thus, went ahead and purchased a new CCV system. Upon removing the air intake, I broke the lower part of the "F" connector connecting to the fuel filter (the fuel relief valve/hose I believe after researching). I bought a new "F" connector, and replaced the vacuum hose on both ends of the fuel relief thing. When I cleaned the Idle Control Valve, it didn't make any noise, like it got stuck or something, but I thought it was normal so I re-installed everything.
Car ran great, idle was steady and consistent (it was already fine before), when the Service Engine light came on. Took it to Advanced Auto, they ran the code P0444. I searched the internet, and I am suspecting that the hose I got to replace the fuel relief valve is too big. I have new hose on order (3.5mm), waiting to replace it to see if that works.
However, I bought a Peake tool to reset the service light and use it for future diagnostics, and it reads Code 20 and 2772, which are Idle Control Valve Stuck Mechanically and TEV Controller. The latter, I assume is the same or similar to the previous P0444 code, and I am hoping the new hose will fix that. The ICV being stuck, however, makes no sense. I've never had a rough/hunter idle, acceleration has always been smooth, and the car continues to drive the same as it ever has even after all of the work. I thought it was strange that the ICV wouldn't make noise when rotating it when I re-installed it, so I took it out this morning, sprayed carb cleaner in it, and it appears to be working properly now(the flap is unconstricted). Drove around, same ICV and TEV codes.
Is there some sort of relation between these two codes, as the ICV appears to be operating as it always has?
Any input is appreciated!

Edit: After replacing the vacuum hose, the problem persisted. I read something regarding the purge valve, so I went to see if maybe I accidentally did something to the hoses on the purge valve, but as it turns out I had forgotten to secure the clip on the electrical connection to the purge valve, and a CEL would come on every time the connection was jumbled, whoops!
