Abstract
An apparatus and method of detecting movement of a plunger of the solenoid includes detecting a peak (I) in a current signal applied to a coil of the solenoid. A predetermined threshold is added to the current signal applied to the coil of the solenoid to generate a level shifted signal. The level shifted signal and the peak signal are compared to detect movement of a plunger of the solenoid.
