  "textContent": "A variable geometry turbocharger (VGT) of an engine of a vehicle has a VGT mechanism and a VGT actuator connected to the VGT actuator. A controller is connected to the VGT actuator, and is configured to monitor at least one entry condition such as vehicle battery voltage, voltage at the VGT actuator, temperature of the engine, its oil, and its coolant, and exhaust gas temperature. If the entry conditions are met, the controller performs a learn procedure in which the VGT actuator cycles the VGT mechanism through its range of motion following a key-off shutdown command. The learn procedure may take place immediately preceding, during, or immediately following shutdown of the engine. The VGT actuator then reports to the controller an available range of motion of the VGT actuator and of the VGT mechanism.",
