A method of controlling a device having restricted movement. A controller is provided for controlling the operation of the device using a control algorithm. A normal operation control method is programmed onto the controller and is selectively activated by the controller to generate a normal control signal. A forcing control method is also programmed into the controller and selectively activates a forcing control signal. The normal operation control signal provides regular operation of the device, while the forcing control signal causes the device to operate in a manner that will correct the operation of the device when a restricted motion of the device is detected.

Control algorithm for freeing an EGR valve from contamination adhesion

A method of using a mid-position lock VCT phaser in an engine with a stop-start mode of operation with the steps of: when the engine is in a stop mode of the stop-start mode: adjusting a duty cycle of an actuator coupled to the control valve of the phaser to command the control valve to the retard mode; maintaining the duty cycle of the actuator to command the control valve to remain in the retard mode until an automatic restart of the engine. If the key is detected in an off position either restarting the engine; commanding the phaser to the detent mode, such that the lock pin is moved to a locked position and the phaser is locked in an intermediate phase angle position; and shutting down the engine or commanding the phaser to detent mode during engine cranking during a next engine restart.
