Diagnostic Procedure with Diagnostic Trouble Code (DTC)
ENGINE (DIAGNOSTICS)
Step Check Yes No
1CHECK CURRENT DATA.
1) Start the engine.
2) Read the data of fuel temperature sensor
signal using Subaru Select Monitor.
NOTE:•Subaru Select Monitor
For detailed operation procedures, refer to
“READ CURRENT DATA FOR ENGINE”. to EN(H6DO)(diag)-26, Subaru Select Moni-
tor.>
Is the temperature less than -
40°C (-40°F)?
Go to step 2.Repair the poor
contact.
NOTE:
In this case, repair
the following item:
•Poor contact
in fuel pump
connector
•Poor contact
in ECM connec-
tor
•Poor contact
of coupling con-
nector
•Poor contact
of joint connec-
tor
2 CHECK HARNESS BETWEEN FUEL TEM-
PERATURE SENSOR AND ECM CONNEC-
TOR.
1) Turn the ignition switch to OFF.
2) Remove the access hole lid.
3) Disconnect the connector from fuel pump.
4) Measure the voltage between fuel pump
connector and chassis ground.
Connector & terminal
(R58) No. 2 (+) — Chassis ground (–):
Is the voltage more than 10 V? Repair the battery
short circuit of har-
ness between
ECM and fuel
pump connector.
Go to step 3.
3 CHECK HARNESS BETWEEN FUEL TEM-
PERATURE SENSOR AND ECM CONNEC-
TOR.
1) Turn the ignition switch to ON.
2) Measure the voltage between fuel pump
connector and chassis ground.
Connector & terminal
(R58) No. 2 (+) — Chassis ground (–):
Is the voltage more than 10 V? Repair the battery
short circuit of har-
ness between
ECM and fuel
pump connector.
Go to step 4.
4 CHECK HARNESS BETWEEN FUEL TEM-
PERATURE SENSOR AND ECM CONNEC-
TOR.
Measure the voltage between fuel pump con-
nector and chassis ground.
Connector & terminal
(R58) No. 2 (+) — Chassis ground (–):
Is the voltage more than 4 V? Go to step 5.Repair the har-
ness and connec-
tor.
NOTE:In this case, repair
the following item:
•Open circuit
of harness be-
tween ECM and
fuel pump con-
nector
•Poor contact
in fuel pump
connector
•Poor contact
in ECM connec-
tor
•Poor contact
of coupling con-
nector

5 CHECK HARNESS BETWEEN FUEL TEM-
PERATURE SENSOR AND ECM CONNEC-
TOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from ECM.
3) Measure the resistance of harness
between fuel pump connector and ECM.
Connector & terminal
(R58) No. 3 — (B135) No. 30:
Is the resistance less than 1
Ω?
Replace the fuel
temperature sen-
sor. EC(H6DO)-8, Fuel

Repair the har-
ness and connec-
tor.
NOTE:In this case, repair
the following item:
•Open circuit
of harness be-
tween ECM and
fuel pump con-
nector
•Poor contact
in fuel pump
connector
•Poor contact
in ECM connec-
tor
•Poor contact
of coupling con-
nector
•Poor contact
of joint connec-
tor
Step Check Yes No
