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 engine and let it idle for 10 seconds.
  2.  Check 1st trip DTC.

Is 1st trip DTC detected? YES >> Proceed to EC-385, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK EXHAUST VALVE TIMING (EVT) CONTROL POSITION SENSOR POWER SUPPLY

  1.  Turn ignition switch OFF.
  2.  Disconnect exhaust valve timing (EVT) control position sensor harness connector.
  3.  Turn ignition switch ON.
  4.  Check the voltage between EVT control position sensor harness connector and ground.

Check exhaust valve timing (EVT) control position sensor power supply

Is the inspection result normal? YES >> GO TO 3.

NO >> GO TO 2.

2.CHECK SENSOR POWER SUPPLY 2 CIRCUIT

Perform EC-484, "Diagnosis Procedure".

Is inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.

NO >> Repair or replace error-detected parts.

3.CHECK EVT CONTROL POSITION SENSOR GROUND CIRCUIT

  1.  Turn ignition switch OFF.
  2.  Disconnect ECM harness connector.
  3.  Check the continuity between EVT control position sensor harness connector and ECM harness connector.

Check EVT control position sensor ground circuit

  1. Also check harness for short to power.

Is the inspection result normal? YES >> GO TO 4.

NO >> Repair or replace error-detected parts.

4.CHECK EVT CONTROL POSITION SENSOR INPUT SIGNAL CIRCUIT

  1.  Disconnect ECM harness connector.
  2.  Check the continuity between EVT control position sensor harness connector and ECM harness connector.

Check EVT control position sensor input signal circuit

  1. Also check harness for short to ground and to power.

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace error-detected parts.

5.CHECK EVT CONTROL POSITION SENSOR

Check the EVT control position sensor. Refer to EC-387, "Component Inspection".

Is the inspection result normal? YES >> GO TO 6.

NO >> Replace EVT control position sensor. Refer to EM-64, "Exploded View".

6.CHECK CAMSHAFT (EXT)

Check the following.

Is the inspection result normal? YES >> GO TO 7.

NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to EM-64, "Removal and Installation".

Check camshaft (EXT)

7.CHECK INTERMITTENT INCIDENT

Refer to GI-41, "Intermittent Incident".

>> INSPECTION END

Component Inspection

1.EXHAUST VALVE TIMING (EVT) CONTROL POSITION SENSOR-1

  1.  Turn ignition switch OFF.
  2.  Disconnect EVT control position sensor harness connector.
  3.  Loosen the fixing bolt of the sensor.
  4.  Remove the sensor.
  5.  Visually check the sensor for chipping.

Is the inspection result normal? YES >> GO TO 2.

NO >> Replace EVT control position sensor. Refer to EM-64, "Exploded View".

Exhaust valve timing (EVT) control position sensor-1

2.EVT CONTROL POSITION SENSOR-2

Check resistance EVT control position sensor terminals as shown below.

EVT control position sensor-2

Is the inspection result normal? YES >> INSPECTION END

NO >> Replace EVT control position sensor. Refer to EM-64, "Exploded View".
