Propulsion for a vehicle is provided by a hybrid powertrain that includes a torque converter coupled to an electric machine and selectively coupled to an engine. The hybrid powertrain further includes a controller programmed to, responsive to a loss of speed feedback of the electric machine while the engine is disconnected from the torque converter and the torque converter is open, operate one or more of a gearbox, the electric machine, and the engine based on an impeller speed of the torque converter derived from a torque of the electric machine and a speed of the vehicle.
