Systems and methods are disclosed for detecting position measurement errors for an electric motor. An exemplary system may include a position sensor configured to measure a position of a rotor of the electric motor. The system may also include an error detector configured to detect an offset between the position measured by the position sensor and an actual position of the rotor. The error detector may include a signal injector configured to inject a probing signal to a stator of the electric motor. The error detector may also include a signal sampler configured to sample a response signal from the stator of the electric motor. The error detector may be configured to derive the offset based on the response signal.
