DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start the engine.

2. Maintain engine speed at 4,500 rpm or more for at least 5 seconds.

3. Check DTC.
Is DTC detected?

YES

>> Proceed to 

EC-1063, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000012198579

EC-1064, "Component Inspection (Engine Oil

Pressure Control Solenoid Valve)"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

Component Inspection (Engine Oil Pressure Control Solenoid Valve)

INFOID:0000000012198580

1.

CHECK ENGINE OIL PRESSURE CONTROL SOLENOID VALVE-1

1. Turn ignition switch OFF.

2. Disconnect engine oil pressure control solenoid valve harness connector.

3. Check resistance between engine oil pressure control solenoid valve terminals as follows.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace engine oil pressure control solenoid valve. Refer to 

EM-200, "Exploded View"

.

2.

CHECK ENGINE OIL PRESSURE CONTROL SOLENOID VALVE-2

1. Remove engine oil pressure control solenoid valve. Refer to 

EM-200, "Exploded View"

.

2. Provide 12 V DC between engine oil pressure control solenoid valve terminals 1 and 2, and then interrupt

it. Make sure that the plunger moves as shown in the figure.

CAUTION:

Do not apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the

coil in engine oil pressure control solenoid valve.

NOTE:

Always replace O-ring when engine oil pressure control solenoid valve is removed.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace engine oil pressure control solenoid valve. Refer to
