   GO TO 2.

2. CHECK DTC PRIORITY

   If DTC P2015 is displayed with DTC P0643, first perform the trouble diagnosis for DTC 0643

   Is applicable DTC detected?

   YES >>

   Refer to DTC Description.

   NO >>

   GO TO 3

3. PERFORM DTC CONFIRMATION PROCEDURE

   1. Turn ignition switch ON.

   2. Warm up the engine to the normal operating temperature and keep the engine speed at idle for 10 seconds.

      Note:

      Warm up the engine until “COOLAN TEMP/S” on “DATA MONITOR” of CONSULT reaches at least 60°C (140°F).

   3. Keep the engine speed 5,000 rpm for at least 10 seconds under no load.

   4. Check 1st trip DTC.

   Is 1st trip DTC detected?

   YES >>

   Refer to DTC Diagnosis Procedure.

   NO-1 >>

   To check malfunction symptom before repair: Refer to Intermittent Incident.

   NO-2 >>

   Confirmation after repair: INSPECTION END

Dtc Diagnosis Procedure

DTC Diagnosis Procedure

1. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE

   1. Turn ignition switch ON.

   2. Warm up the engine to the normal operating temperature.

      Note:

      Warm up the engine until “COOLAN TEMP/S” on “DATA MONITOR” of CONSULT reaches at least 60°C (140°F).

   3. Fully release accelerator pedal and make sure that “TUMBLE POS SEN” indicates between 3.1 V to 4.7 V.

   4. Keep the engine speed 5,000 rpm that “TUMBLE POS SEN” indicates between 0.3 V to 2.1 V.

   5. Check 1st trip DTC.

   Is 1st trip DTC detected?

   YES >>

   Replace intake manifold. Refer to Removal and Installation.

   NO >>

   GO TO 2.

2. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR CIRCUIT

   1. Turn ignition switch OFF.

   2. Disconnect ECM harness connector and intake manifold runner control valve motor harness connector.

   3. Check the continuity between intake manifold runner control valve motor harness connector and ECM harness connector.

      Intake manifold runner control valve motor		ECM		Continuity
      Connector	Terminal	Connector	Terminal
      F70	1	F25	91	Existed
      			92	Not existed
      	2		91	Not existed
      			92	Existed

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

   Is the inspection result normal?

   YES >>

   GO TO 3.

   NO >>

   Repair or replace malfunctioning part.

3. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE

   Check intake manifold runner control valve. Refer to Component Inspection.

   Is the inspection result normal?

   YES >>

   GO TO 4

   NO >>

   Replace intake manifold. Refer to Removal and Installation.

4. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR CIRCUIT

   1. Turn ignition switch OFF.

   2. Disconnect ECM harness connector and intake manifold runner control valve position sensor harness connector.

   3. Check the continuity between intake manifold runner control valve position sensor harness connector and ECM harness connector.

      +		−		Continuity
      Intake manifold runner control valve position sensor		ECM
      Connector	Terminal	Connector	Terminal
      F29	1	F25	83	Existed
      	2		82
      	3		79

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

   Is the inspection result normal?

   YES >>

   GO TO 5.

   NO >>

   Repair or replace malfunctioning part.

5. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR

   Check intake manifold runner control valve position sensor. Refer to Component Inspection.

   Is the inspection result normal?

   YES >>

   INSPECTION END

   NO >>

   Replace intake manifold. Refer to Removal and Installation.
