A vehicle includes an electric machine having a rotor and a stator, a resolver that measures a position of the rotor relative to the stator, and a controller. The controller, based on the position and a resolver offset, injects a first current having only a d-axis component into the electric machine, and responsive to detecting a first motion output of the electric machine being greater than a threshold, adjusts the resolver offset according to a magnitude and direction of the first motion output.
