Abstract
Methods and systems are provided for adjusting vehicle grille shutters based on engine coolant temperature. In one example, a method includes adjusting grille shutters based on engine coolant temperature and additional engine operating conditions when engine coolant temperature is below a threshold and adjusting the grille shutters base on the engine coolant temperature only when the engine coolant temperature is above the threshold. Further, the method may include recalibrating a position of the grille shutters based on a grille shutter position error.
