DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK CURRENT DATA. Start the engine. Read the data of fuel temperature sensor signal using Subaru Select Monitor. NOTE: Subaru Select Monitor For detailed operation procedure, refer to "READ CURRENT DATA FOR ENGINE". < Ref. to SUBARU SELECT MONITOR . >	Is the fuel temperature above 150°C(302°F)?	Go to step 2.	Even if the malfunction indicator light illuminates, the circuit has returned to a normal condition at this time.
2 CHECK CURRENT DATA. Turn the ignition switch to OFF. Remove the access hole lid. Disconnect the connector from fuel pump. Turn the ignition switch to ON. Read the data of fuel temperature sensor signal using Subaru Select Monitor. NOTE: Subaru Select Monitor For detailed operation procedure, refer to "READ CURRENT DATA FOR ENGINE". < Ref. to SUBARU SELECT MONITOR . >	Is the fuel temperature less than -40°C (-40°F) ?	Replace the fuel temperature sensor. < Ref. to FUEL TEMPERATURE SENSOR . >	Repair the ground short circuit of the harness between fuel injector and ECM connector.
