Abstract
An assembly includes an inlet tube and an outlet tube. The assembly includes 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 has a spring urging the plunger to the closed position. The assembly includes 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. The assembly includes 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.
