Abstract
A method for controlling a wastegate valve of a turbocharger and the turbocharger of a vehicle are disclosed. The method includes (a) receiving a closed position request; (b) moving an actuator toward a previously stored closed position until a predetermined actuator position is reached, the actuator being operatively connected to the wastegate valve for actuating the wastegate valve; (c) receiving an actual value indicative of force exerted by the actuator; and (d) comparing the actual value to an expected value indicative of force exerted by the actuator; in response to the actual value being less than the expected value, (e) moving the actuator away from an open position by a predetermined amount; (f) replacing the previously stored closed position with a position of the actuator following step (e); and (g) repeating steps (d) to (f) until the actual value is greater than the expected value.
