Location of the fuel actuator (right side top engine view) (1) Fuel actuatorFuel actuator (1) is electronically controlled and electrically actuated. The fuel actuator and the ECM communicate via the CAN data link.Throttle Actuator
Illustration 3 g01917653
Location of the throttle actuator (left side top engine view) (2) Throttle actuatorThrottle actuator (2) is electronically controlled and electrically actuated. The ECM issues commands to the actuator via the CAN data link.Engine Sensors
Sensors provide information to the ECM. The information is used for monitoring engine operation. The information enables the ECM to control the engine as efficiently as possible over a wide range of operating conditions. The sensors provide signals to the ECM that are used in the determination of the states of engine alarms and of engine shutdowns. These conditions may be in response to abnormal operation or to a command that is initiated by the operator.
