Abstract
An engine control system comprises a current control module and a solenoid actuator module. The current control module determines a duty cycle based on a desired current through a solenoid of an engine system and a resistance of the solenoid and corrects the resistance based on an actual current through the solenoid. The solenoid actuator module actuates the solenoid based on the duty cycle.
