Abstract
The present invention relates to a method and system for determining the position of the armature of a solenoid using a controller to determine the temperature of the solenoid and to indirectly determine the position of the armature without the need of an additional sensor using current sensing pulses and a solenoid capable of staying engaged due to residual magnetism after the coil has been de-energized.
