A control unit, controller and non-transitory machine-readable medium for detecting a closing time of an injector valve are disclosed. The control unit is configured to receive a valve current profile of the injector valve, process the valve current profile using at least a slope discriminator, and determine a stuck status and a closing time (if applicable) of the injector valve based on an output of the slope discriminator.
