CHECK STARTING SYSTEM
Turn ignition switch to START position.

Does the engine turn over? Does the starter motor operate?

YES

GO TO 2.

NO

Check starting system. (Refer to Work Flow .)

CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY

Turn ignition switch ON.

Check the voltage between CMP sensor (PHASE) harness connector and ground.

+			-	Voltage (Approx.)
CMP sensor (PHASE)
Bank	Connector	Terminal
1	F66	3	Ground	Battery voltage

Is the inspection result normal?

YES

GO TO 4.

GO TO 3.

CHECK CMP SENSOR (PHASE) POWER SUPPLY CIRCUIT

Turn ignition switch OFF.
