STEP 1. Using scan tool (M.U.T.-IIISE), check actuator test item 13: Intake Engine Oil Control Valve ON.
STEP 2. Check the intake engine oil control valve.
(1) Disconnect the intake engine oil control valve connector and measure at intake engine oil control valve side.
(2) Measure the resistance between intake engine oil control valve side connector terminals.Standard value: 6.9 - 7.9 ohms [at 20°C (68°F)]
Is the measured resistance between 6.9 and 7.9 ohms [at 20°C (68°F)]?
Go to Step 3. Replace the intake engine oil control valve. Then go to Step 8.
STEP 3. Measure the power supply voltage at intake engine oil control valve harness side connector.
(1) Disconnect the intake engine oil control valve connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal power supply line and ground.- Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is battery positive voltage (approximately 12 volts) present?
Go to Step 4. Repair or replace the connector(s), or check and repair the harness of short to ground and open circuit in power supply line between MFI relay connector and intake engine oil control valve connector. Then go to Step 8.
STEP 4. Measure the power supply voltage at ECM connector.
(1) Disconnect the ECM connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal OCVI and ground.- Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is battery positive voltage (approximately 12 volts) present?
Go to Step 5. Repair or replace the connector(s), or check and repair the harness of short to ground and open circuit in OCVI line between intake engine oil control valve connector and ECM connector. Then go to Step 8.
STEP 5. Check of harness damage in power supply line between MFI relay connector and intake engine oil control valve connector.
STEP 6. Check of harness damage in OCVI line between intake engine oil control valve connector and ECM connector.
STEP 7. Using scan tool (M.U.T.-IIISE), check actuator test item 13: Intake Engine Oil Control Valve ON.
STEP 8. Test the OBD-II drive cycle.
(1) Carry out test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 8 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0010 set?
Retry the troubleshooting. The inspection is complete.
