Engine Fuel Temperature Sensor 1 Circuit - Marine En


Circuit Description


The engine fuel temperature sensor 1 is used by the engine control module (ECM) to monitor engine fuel supply temperature. The ECM monitors the voltage on the engine fuel temperature signal pin and converts this to a temperature value. The engine fuel temperature value is used by the ECM for the engine protection system.

Component Location


The engine fuel temperature sensor 1 is located on the fuel filter housing. Use the following procedure for a detailed component location view. Refer to Procedure 100-002 in Section E.
