DIAGNOSIS PROCEDURE
| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK CURRENT DATA.
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) ? | Go to step 2. | Repair the poor contact.
NOTE:
In this case, repair the following item:
|
2 CHECK HARNESS BETWEEN FUEL TEMPERATURE SENSOR AND ECM CONNECTOR.
|
Is the voltage more than 10 V? | Repair the battery short circuit of harness between ECM and fuel pump connector. | Go to step 3. |
3 CHECK HARNESS BETWEEN FUEL TEMPERATURE SENSOR AND ECM CONNECTOR.
|
Is the voltage more than 10 V? | Repair the battery short circuit of harness between ECM and fuel pump connector. | Go to step 4. |
| 4 CHECK HARNESS BETWEEN FUEL TEMPERATURE SENSOR AND ECM CONNECTOR. Measure the voltage between fuel pump connector and chassis ground. Connector & terminal (R58) No. 2 (+) - Chassis ground (-): |
Is the voltage more than 4 V? | Go to step 5. | Repair the harness and connector.
NOTE:
In this case, repair the following item:
|
5 CHECK HARNESS BETWEEN FUEL TEMPERATURE SENSOR AND ECM CONNECTOR.
|
Is the resistance less than 1 Ω? | Replace the fuel temperature sensor. < Ref. to FUEL TEMPERATURE SENSOR . > | Repair the harness and connector.
NOTE:
In this case, repair the following item:
