The ACC will not change the voltage because it's desperately trying to close the monovalve because the driver is roasting.
The monovalve, however, is not cooperating.
So, pull the monovalve and look for obvious signs of binding of the valve or damage to the valve. If you can't find anything obvious, then the solenoid is probably toast and you must replace the entire valve.
I doubt the problem is a bad diaphragm as evidenced by the presence of maximum heat.
The one other possibility is the plug. You may measure 13V with your meter, but, if the sockets have corrosion, the valve is not getting the 13V. Try putting 12V and ground directly to the valve with jumper wires and see if you can get the valve to close.
