Abstract
A method of verifying proper operation of an electromagnetic valve. The method includes providing a mechanism to effect opening of the valve, verifying that the valve opened as a result of employing the mechanism to effect opening of the valve and after verifying the valve opened, signaling the valve to close after a first period of time has elapsed. The method further includes, after signaling the valve to close, signaling the valve to re-open after a second period of time has elapsed and detecting the occurrence or non-occurrence of an event associated with the closing or re-opening of the valve.
