Abstract

A solenoid valve in a manifold is commanded to move to a closed position. Upon activating a pump to supply fluid to the manifold via a supply line, a first pressure is determined in the supply line after commanding the solenoid valve to move to the closed position. Upon deactivating the pump to stop supplying fluid to the manifold, a second pressure is determined in the supply line. Based on a difference between the first pressure and the second pressure, the solenoid valve is determined to be one of (a) at least partially open or (b) in the closed position.
