1. An assembly, comprising:
an inlet tube;
an outlet tube; and
a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube;
the solenoid assembly having a spring urging the plunger to the closed position;
a first pressure sensor positioned to be compressed when the plunger is moved toward the open position, pressure detected by the first pressure sensor indicates whether the plunger is at the open position; and
a second pressure sensor positioned to be compressed when the plunger is moved toward the closed position, pressure detected by the second pressure sensor indicates whether the plunger is at the closed position.
