Abstract: A system and method for monitoring analog front-end (AFE) circuitry of an inductive position sensor. A redundant AFE channel is provided and alternatively utilized with a sine AFE channel or a cosine AFE channel of the AFE circuitry to obtain a voltage difference that may result in a detection angle error at the electronic control unit (ECU) of the inductive position sensor.
