2. Provide 12 V DC between intake valve timing 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 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
>> INSPECTION END
NO
>> Replace intake valve timing control solenoid valve. Refer to
.

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 TO2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and let it idle for 5 seconds.
2. Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000012197771
1.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect exhaust valve timing (EVT) control solenoid valve harness connector.
3. Turn ignition switch ON.
4. Check the voltage between exhaust valve timing control solenoid valve harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> GO TO 2.
2.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector.
3. Check the continuity between EVT control solenoid valve harness connector and IPDM E/R harness con-
nector.
DTC No.

4. Also check harness for short to ground.
Is the inspection result normal?
YES
>> Perform the trouble diagnosis for power supply circuit.
NO
>> Repair or replace error-detected parts.
3.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between EVT control solenoid valve harness connector and ECM harness connec-
tor.
4. Also check harness for short to ground and to power.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair or replace error-detected parts.
4.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE
Check the exhaust valve timing control solenoid valve. Refer to
EC-212, "Component Inspection"
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Replace exhaust valve timing control solenoid valve.
Component Inspection
INFOID:0000000012197772
1.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-I
1. Turn ignition switch OFF.
2. Disconnect exhaust valve timing control solenoid valve harness connector.
3. Check resistance between exhaust valve timing control solenoid valve terminals as per the following.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Replace exhaust valve timing control solenoid valve. Refer to
.
2.
CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II
