The invention relates to a sensor protection circuit for at least one sensor ( 6 ), especially in a motor vehicle electric system, comprising at least one supply line ( 3, 4 ) for supplying current to the sensor ( 6 ) and a current measuring unit ( 8 ) for detecting the electric current flowing through the supply line ( 3 ), in order to prevent damage to the sensor ( 6 ) as a result of excess voltage. Said current measuring unit ( 8 ) is connected to a current limiting device or to a switch element in order to limit the current or to disconnect the supply line ( 3 ).
