Diagnosis Procedure

INFOID:0000000005536543

1.

CHECK OIL PRESSURE WARNING LAMP

1.

Start engine.

2.

Check oil pressure warning lamp and confirm it is not illumi-
nated.

Is oil pressure warming lamp illuminated?

YES

>> Go to 

LU-7, "Inspection"

.

NO

>> GO TO 2.

2.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE

Refer to 

EC-142, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace malfunctioning intake valve timing control solenoid valve.

3.

CHECK CRANKSHAFT POSITION SENSOR (POS)

Refer to 

EC-257, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace crankshaft position sensor (POS).

4.

CHECK CAMSHAFT POSITION SENSOR (PHASE)

Refer to 

EC-260, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace malfunctioning camshaft position sensor (PHASE).

5.

CHECK CAMSHAFT (INTAKE)

Check the following.

ENG SPEED

1,400 - 3,175 rpm (A constant rotation is maintained.)

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Remove debris and clean the signal plate of camshaft

rear end or replace camshaft.

6.

CHECK TIMING CHAIN INSTALLATION

Check service records for any recent repairs that may cause timing chain misalignment.

Are there any service records that may cause timing chain misalignment?

YES

>> Check timing chain installation. Refer to

Component Inspection

INFOID:0000000005536544

1.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I

1.

Disconnect intake valve timing control solenoid valve harness connector.

2.

Check resistance between intake valve timing control solenoid valve terminals as per the following.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace malfunctioning intake valve timing control solenoid valve.

2.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II

1.

Remove intake valve timing control solenoid valve.

2.

Provide 12 V DC between intake valve timing control solenoid
valve terminals 1 and 2, and then interrupt it. Check that the
plunger moves as shown in the figure.

CAUTION:

Never apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed.

Is the inspection result normal?

YES
