Abstract

A system and method include measuring input electric current that is input into an electrically controlled valve to change a position of the valve. Output electric current that is output from the valve in response to the input electric current being input into the electrically controlled valve is measured. Position signals are generated using a sensor coupled with the electrically controlled valve that are indicative of the position of the valve. Baseline values associated with the input electric current, the output electric current, and the position signals are calculated. A health state of the valve is determined by comparing the baseline values associated with the input electric current, the output electric current, and the position signals with subsequently measured values associated with the input electric current, the output electric current, and the position signals.
