Abstract
An engine oil change detection control system is provided. The system includes an armature position module that monitors a solenoid armature position based on a position signal. A solenoid control module selectively generates a solenoid control signal and estimates a delay time based on the solenoid control signal and the armature position. An engine oil change detection module detects an engine oil change event based on the delay time.
