| CHECK HARNESS BETWEEN ECM AS WELL AS MAIN RELAY AND INTAKE OIL FLOW CONTROL SOLENOID VALVE LH CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connectors from ECM and intake oil flow control solenoid valve LH. 3) Remove the main relay. 4) Measure the resistance of harness between ECM and main relay connector and intake oil flow control solenoid valve LH connector. Connector & terminal (B220) No. 38 — (E37) No. 1: (B134) No. 34 — (E37) No. 2: |
| QUESTION | |
|
Is the resistance less than 1 Ω? | |
| Yes | No |
|
|
Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit in harness between ECM and intake oil flow control solenoid valve LH connector • Open circuit in harness between main relay and intake oil flow control solenoid valve LH connector • Poor contact of coupling connector |
