May only be a one-time thing owing to a small particle of something getting jammed in the solenoid. The code may disappear by itself.
If it doesn't right away, check out the color of your tranny fluid. If it is pretty much red or brown and smells ok, then flush the tranny and see if that gets rid of the code. If not, pull out some fluid and add a bottle of Seafoam Trans Tune and run it for 1 or 2k miles. Then flush the transmission again. Check if the code is gone.
If this problem persists, I've been told you'll have to replace the solenoid.
Possible causes are:
* Solenoid is stuck open or closed.
* Valve body clogged or valve stuck.
A Toyota service tech can check the system without pan removal with his analyzer.
