  • DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

  • Inhibits the engine oil control.

POSSIBLE CAUSE

  • Engine oil solenoid valve connector or terminals malfunction

  • Short to ground or open circuit in engine oil solenoid valve power supply circuit

    • Short to ground in wiring harness between ENGINE2 15 A fuse and engine oil solenoid valve terminal A

    • ENGINE2 15 A fuse malfunction

    • Open circuit in wiring harness between main relay terminal C and engine oil solenoid valve terminal A

  • Short to ground in wiring harness between engine oil solenoid valve terminal B and PCM terminal 1AS

  • PCM connector or terminals malfunction

  • Short to power supply in wiring harness between engine oil solenoid valve terminal B and PCM terminal 1AS

  • Open circuit in wiring harness between engine oil solenoid valve terminal B and PCM terminal 1AS

  • Engine oil solenoid valve malfunction

  • PCM malfunction

Diagnostic Procedure

STEP

INSPECTION

ACTION

1

 RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION

NOTE:

  • Recording can be facilitated using the screen capture function of the PC.

  • Record the snapshot data on the repair order.

—

Go to the next step.

2

 VERIFY RELATED REPAIR INFORMATION AVAILABILITY

  • Verify related Service Bulletins and/or on-line repair information availability.

  • Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

  • If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

 INSPECT ENGINE OIL SOLENOID VALVE CONNECTOR CONDITION

  • Switch the ignition off.

  • Disconnect the engine oil solenoid valve connector.

  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

  • Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 10.

No

Go to the next step.

4

 INSPECT ENGINE OIL SOLENOID VALVE POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT

  • Verify that the engine oil solenoid valve connector is disconnected.

  • Switch the ignition ON (engine off).

    NOTE:

    • Another DTC may be stored by the PCM detecting an open circuit.

  • Measure the voltage at the engine oil solenoid valve terminal A (wiring harness-side).

  • Is the voltage B+?

Yes

Go to the next step.

No

Inspect the ENGINE2 15 A fuse.

  • If the fuse is blown:

    • Refer to the wiring diagram and verify whether or not there is a common connector between ENGINE2 15 A fuse and engine oil solenoid valve terminal A.

        • If there is a common connector:

      • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.

      • Repair or replace the malfunctioning part.

        If there is no common connector:

      • Repair or replace the wiring harness which has a short to ground.

      • Replace the fuse.

  • If the fuse is damaged:

    • Replace the fuse.

  • If the fuse is normal:

    • Refer to the wiring diagram and verify whether or not there is a common connector between main relay terminal C and engine oil solenoid valve terminal A.

        • If there is a common connector:

      • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

      • Repair or replace the malfunctioning part.

        If there is no common connector:

      • Repair or replace the wiring harness which has an open circuit.

Go to Step 10.

5

 INSPECT ENGINE OIL SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO GROUND

  • Verify that the engine oil solenoid valve connector is disconnected.

  • Switch the ignition off.

  • Inspect for continuity between engine oil solenoid valve terminal B (wiring harness-side) and body ground.

  • Is there continuity?

Yes

Disconnect the PCM connector and inspect the wiring harness for short to ground.

  • If the short to ground circuit could be detected in the wiring harness:

    • Refer to the wiring diagram and verify whether or not there is a common connector between engine oil solenoid valve terminal B and PCM terminal 1AS.

        • If there is a common connector:

      • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.

      • Repair or replace the malfunctioning part.

        If there is no common connector:

      • Repair or replace the wiring harness which has a short to ground.

Go to Step 10.

No

Go to the next step.

6

 INSPECT PCM CONNECTOR CONDITION

  • Disconnect the PCM connector.

  • Inspect for poor connection (such as damaged/pulled-out pins, corrosion).

  • Is there any malfunction?

Yes

Repair or replace the connector and/or terminals, then go to Step 10.

No

Go to the next step.

7

 INSPECT ENGINE OIL SOLENOID VALVE CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY

  • Verify that the engine oil solenoid valve and PCM connectors are disconnected.

  • Switch the ignition ON (engine off).

    NOTE:

    • Another DTC may be stored by the PCM detecting an open circuit.

  • Measure the voltage at the engine oil solenoid valve terminal B (wiring harness-side).

  • Is the voltage 0 V?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between engine oil solenoid valve terminal B and PCM terminal 1AS.

    If there is a common connector:

  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.

  • Repair or replace the malfunctioning part.

    If there is no common connector:

  • Repair or replace the wiring harness which has a short to power supply.

Go to Step 10.

8

 INSPECT ENGINE OIL SOLENOID VALVE CONTROL CIRCUIT FOR OPEN CIRCUIT

  • Verify that the engine oil solenoid valve and PCM connectors are disconnected.

  • Switch the ignition off.

  • Inspect for continuity between engine oil solenoid valve terminal B (wiring harness-side) and PCM terminal 1AS (wiring harness-side).

  • Is there continuity?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between engine oil solenoid valve terminal B and PCM terminal 1AS.

    If there is a common connector:

  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

  • Repair or replace the malfunctioning part.

    If there is no common connector:

  • Repair or replace the wiring harness which has an open circuit.

Go to Step 10.

9

 INSPECT ENGINE OIL SOLENOID VALVE

Yes

Replace the engine oil solenoid valve, then go to the next step.

(See ENGINE OIL SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

No

Go to the next step.

10

 VERIFY DTC TROUBLESHOOTING COMPLETED

Yes

Repeat the inspection from Step 1.

Go to the next step.

No

Go to the next step.

11

 VERIFY AFTER REPAIR PROCEDURE

Yes

Go to the applicable DTC inspection.
