In one of these links, I think it's a ways down, there is info on how many ohms etc to see at X degrees etc etc. You can use that to test the wiring to the soleniods as well as getting a ballpark if the soleniods are bad etc.
Since you are getting this code, it would seem that the pcm is seeing the tcc sticking or being commanded etc. ... checking on a hunch about how the release happens, I came across this.

Might give you the info you need to fully figure out which part is bad.
