This sensor monitors a parameter within the electrical system of the host machine. It is installed at a specific point in the wiring harness to provide a signal to the control unit. When the sensor fails or its signal is lost, the control unit may log a fault code and the operator will see a warning on the display. The sensor is an original component, meaning its electrical characteristics and connector geometry match the factory-installed unit, ensuring the control unit receives the correct signal without the need for wiring modifications.
