2. Turn ignition switch ON.
3. Check the voltage between VVEL control shaft position sensor harness connector and ground.

   VVEL control shaft position sensor			Ground	Voltage
   Bank	Connector	Terminal
   1	F72	3	Ground	Approx. 5 V
   		6
   2	F70	3
   		6

   Is the inspection result normal? 

   YES: GO TO  6.

   NO: GO TO 2.

1. Turn ignition switch OFF.
2. Disconnect VVEL control module harness connector.
3. Check the continuity between VVEL control shaft position sensor harness connector and VVEL control module harness connector.

   VVEL control shaft position sensor			VVEL control module		Continuity
   Bank	Connector	Terminal	Connector	Terminal
   1	F72	3	E15	7	Existed
   		6		20
   2	F70	3		9
   		6		22

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

   Is the inspection result normal? 

   YES: GO TO  4.

   NO: GO TO 3.

Check the following.

• Harness for open or short between VVEL control shaft position sensor and VVEL control module
• Loose or poor connection for each connector and harness

  : Repair open circuit, short to ground or short to power in harness or connectors.

Refer to "INTERMITTENT INCIDENT ".

Is the inspection result normal? 

YES: GO TO 5.

NO: Repair or replace.

1. Replace VVEL control module. Refer to "REMOVAL AND INSTALLATION ".
2. Perform additional service when replacing VVEL control module. Refer to "WORK PROCEDURE ".
