The invention provides a current sensing module, a vehicle-mounted system and a method for current sensing and fault diagnosis. The current sensing module comprises a shunt resistor for receiving and sensing current, a digital sensing circuit and an analog sensing circuit. The shunt resistor includes a connection portion, a first resistance portion, and a second resistance portion coupled in series to the first resistance portion via the connection portion. The digital sensing circuit is coupled to the first resistor part and is used for measuring a first analog voltage of the first resistor part when the current flows through the first resistor part and providing a first digital measurement value related to the first analog voltage. The analog sensing circuit is coupled to the second resistor portion and is used for measuring a second analog voltage of the second resistor portion when the current flows through the second resistor portion and providing a second analog measurement value related to the second analog voltage.
