STEP 1. Using scan tool (M.U.T.-IIISE), check actuator test item 17: Engine Oil Control Valve.
STEP 2. Check the engine oil control valve.
(1) Disconnect the engine oil control valve connector and measure at engine oil control valve side.
(2) Measure the resistance between 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 engine oil control valve. Then go to Step 8.
STEP 3. Measure the power supply voltage at engine oil control valve harness side connector.
(1) Disconnect the engine oil control valve connector and measure at the harness side.
(2) Turn on the power supply mode of the electric motor switch.
(3) Measure the voltage between terminal power supply line and ground.- Voltage should be 12V starter battery positive voltage.
(4) Turn off the power supply mode of the electric motor switch.
Is 12V starter 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 engine oil control valve connector. Then go to Step 8.
STEP 4. Measure the power supply voltage at ECM connector by using power plant ECU check harness special tool MB992110.
(1) Disconnect all ECM connectors. Connect the power plant ECU check harness special tool MB992110 between the separated connectors.
(2) Turn on the power supply mode of the electric motor switch.
(3) Measure the voltage between terminal OCVI and ground.- Voltage should be 12V starter battery positive voltage.
(4) Turn off the power supply mode of the electric motor switch.
Is 12V starter 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 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 engine oil control valve connector.
STEP 6. Check of harness damage in OCVI line between engine oil control valve connector and ECM connector.
STEP 7. Using scan tool (M.U.T.-IIISE), check actuator test item 17: Engine Oil Control Valve.
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 4 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0010 set?
Retry the troubleshooting. The inspection is complete.
