UENR0623-02 45 Engine Operation Illustration 41 g03360457 Schematic for the temperature sensors for the 854F-E34T (model JS) engine and 854F-E34T (model JT) engine The air inlet temperature sensor and the coolant temperature sensor are passive sensors. Each sensor provides a temperature input to the ECM. The ECM controls following operations: The solenoid for the wastegate Diagnostic connector Fuel delivery Electronic unit injectors Injection timing The glow plugs are powered directly from the battery. The sensors are also used for engine monitoring. i05292810 Power Sources Introduction The engine supplies power to the ECM. The ECM powers the following components:
All sensors The control valve for the fuel injection pump
