Abstract: Disclosed is a method and device for diagnosis of functioning faults caused by the angular position measurement sensors of the rotor of a polyphase rotary electrical machine comprising a stator, in particular of the alternator-starter type. The diagnosis is obtained by carrying out direct measurements of pairs of sine and cosine signals determined on the basis of linear combinations of the polyphase signals provided by these sensors. This measurement therefore does not make it necessary to know the exact value of the speed of the machine. The diagnosis of functioning faults caused by the angular position measurement sensors requires only the execution of elementary logic operations, i.e. the determination of the “true” or “false” logic states of two inequality equations.
