A control system for monitoring operation of an electric motor includes a plurality of position sensors configured to measure a position of the electric motor, an indirect position estimation module configured to indirectly estimate the position of the motor, and an error monitoring module. The error monitoring module is configured to perform at least one of: comparing a measured position from the plurality of position sensors to an estimated position from the sensor position estimation module, and detecting a failure of at least one of the one or more position sensors based on the comparison; and calculating a difference between the measured position from one of the plurality of position sensors and the measured position from another of the plurality of position sensors, and causing the indirect position estimation module to initiate estimation of the position of the motor based on the difference.
