Engine Oil Solenoid Valve Control Inspection

1. Verify that the oil pressure is normal. (See OIL PRESSURE INSPECTION [SKYACTIV-D 1.8].)

2. Connect the M-MDS to the DLC-2.

3. Start the engine.

4. Access the PID/DATA monitor items OIL_PUMP_DUTY, ENG_RPM and ECT. (See PID/DATA MONITOR INSPECTION.)(See PID/DATA MONITOR TABLE [PCM (SKYACTIV-D)].)

5. When the following conditions are met, verify the oil pressure gauge value changes:

• Engine coolant temperature (PID: ECT): 100 °C{212 °F} or more.

• Engine speed: 2,100 rpm or more.

• OIL_PUMP_DUTY PID value is changing.

― If the oil pressure gauge value does not change:

• Inspect the engine oil solenoid valve. (See Engine Oil Solenoid Valve Operation Inspection.)

― If the oil pressure gauge value changes:

• Engine oil solenoid valve is normal.

Engine Oil Solenoid Valve Operation Inspection

1. Remove the engine oil solenoid valve. (See ENGINE OIL SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

2. Verify that the battery is fully charged.

3. Connect the battery to the engine oil solenoid valve connector (2 terminals) as shown in the figure.

4. Verify that there is an operation sound from the engine oil solenoid valve when applying battery voltage between engine oil solenoid valve connector terminals A and B.

• If the operation sound cannot be heard, replace the engine oil solenoid valve. (See ENGINE OIL SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

Note

• A click sound is heard when the engine oil solenoid valve operates normally.

5. Install the engine oil solenoid valve. (See ENGINE OIL SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)
