1.CHECK HARNESS BETWEEN ECM AND INTAKE OIL FLOW CONTROL SOLENOID VALVE LH.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from ECM and intake oil flow control solenoid valve LH.
3) Measure the resistance of harness between ECM and intake oil flow control solenoid valve LH connector.
Connector & terminal
(B134) No. 34 — (E67) No. 2:
|
Is the resistance less than 1 Ω?
|
|
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
• Poor contact of coupling connector
|
2.CHECK HARNESS BETWEEN ECM AND INTAKE OIL FLOW CONTROL SOLENOID VALVE LH.
Measure the resistance between ECM and chassis ground.
Connector & terminal
(B134) No. 34 — Chassis ground:
|
Is the resistance 1 MΩ or more?
|
|
Repair the short circuit to ground in harness between ECM and intake oil flow control solenoid valve LH connector.
|
3.CHECK INTAKE OIL FLOW CONTROL SOLENOID VALVE LH.
Measure the resistance between intake oil flow control solenoid valve LH terminals.
|
Is the resistance between 6 — 12 Ω?
|
Repair the poor contact of ECM and intake oil flow control solenoid valve LH connector.
|
Replace the intake oil flow control solenoid valve LH.
