Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK GROUND CONNECTION 
   1. Turn ignition switch OFF.
   2. Check ground connection E9. Refer to Ground Inspection in "CIRCUIT INSPECTION ".

      Is the inspection result normal? 

      YES: GO TO 2.

      NO: Repair or replace ground connection.

2. CHECK ACCELERATOR PEDAL POSITION SENSOR 1 POWER SUPPLY CIRCUIT 
   1. Disconnect accelerator pedal position (APP) sensor harness connector.
   2. Turn ignition switch ON.
   3. Check the voltage between APP sensor harness connector and ground.

      APP sensor		Ground	Voltage (V)
      Connector	Terminal
      E40	5	Ground	Approx. 5

      Is the inspection result normal? 

      YES: GO TO  7.

      NO: GO TO 3.

3. CHECK SENSOR POWER SUPPLY CIRCUIT 

   Check harness for short to power and short to ground, between the following terminals.

   ECM		Sensor
   Connector	Terminal	Name	Connector	Terminal
   F13	47	TP sensor	F57	1
   	51	Battery current sensor	F5	1
   	55	PSP sensor	F40	3
   	59	CMP sensor (PHASE) (bank 1)	F55	1
   		EVT control position sensor (bank 1)	F43	1
   	63	CMP sensor (PHASE) (bank 2)	F60	1
   		EVT control position sensor (bank 2)	F42	1
   E10	83	APP sensor	E40	5

   Is the inspection result normal? 

   YES: GO TO 4.

   NO: Repair short to ground or short to power in harness or connectors.
