NO >> INSPECTION END
Diagnosis Procedure
1.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 STR-11, "Work Flow (With GR8-1200 NI)" or STR-15, "Work Flow (Without GR8-1200 NI)").
2.CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.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.
4.CHECK CMP SENSOR (PHASE) GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK CMP SENSOR (PHASE) INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK CAMSHAFT POSITION SENSOR (PHASE)
Check the camshaft position sensor (PHASE). Refer to EC-300, "Component Inspection (Camshaft position sensor)".
Is the inspection result normal? YES >> GO TO 7.
NO >> Replace camshaft position sensor (PHASE). Refer to EM-64, "Removal and Installation".
7.CHECK CAMSHAFT (INT)
Check the following.
Is the inspection result normal? YES >> GO TO 8.
NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to EM-64, "Removal and Installation".
8.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection (Camshaft position sensor)
1.CHECK CAMSHAFT POSITION SENSOR (PHASE)-1
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace camshaft position sensor (PHASE).
2.CHECK CAMSHAFT POSITION SENSOR (PHASE)-2
Check the resistance camshaft position sensor (PHASE) terminals as per the following.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace camshaft position sensor (PHASE). Refer to EM-64, "Removal and Installation".
