ABSTRACT:
A method and system for detecting degraded operation of a solenoid. A current through the solenoid is sampled at predetermined time intervals within a predetermined time period. A maximum value of the sampled current is first detected. Next, a minimum value of the sampled current subsequent to the maximum value is detected. Finally, a predetermined increase in the sampled current from the minimum value is detected to verify operation of the solenoid.
