Fuel Metering Valve
Illustration 3 g01287184
Right side view
(1) Fuel metering valve (typical location)
(2) Alternate location for the fuel metering valve The fuel metering valve is electrically controlled and electrically actuated. The fuel metering valve and the master Electronic Control Module (ECM) communicate via the CAN data link.Actuators

(3) Throttle actuator
(4) Actuator for the compressor bypass valve Throttle actuator (3) and the actuator for the compressor bypass valve (4) are electrically controlled and electrically actuated. The master ECM sends commands to the actuators via the CAN data link.Sensors
Sensors provide information to the electronic control modules. The information enables the modules to control the engine as efficiently as possible over a wide range of operating conditions. The information is used for monitoring engine operation.The sensors also enable the activation of alarms and of shutoffs in response to abnormal operation. Refer to Systems Operation/Testing and Adjusting, "Engine Sensors" for the descriptions of the sensors.

Thermocouples provide information to the Integrated Temperature Sensing Module (ITSM). The information is used to monitor engine operation. The thermocouples also enable alarms and shutoffs to be activated.Illustrations 9 and 10 show the locations of the thermocouples. Refer to Systems Operation/Testing and Adjusting, "Integrated Temperature Sensing Module" for the descriptions of the thermocouples.
