EC-258 < COMPONENT DIAGNOSIS > [VQ35HR] P0340, P0345 CMP SENSOR (PHASE) Diagnosis Procedure INFOID:0000000003133417 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 2. CHECK GROUND CONNECTION 1. Turn ignition switch OFF. 2. Check ground connection M95. Refer to Ground Inspection in Is the inspection result normal? YES >> GO TO 3. NO >> Repair or replace ground connection. 3. CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY CIRCUIT-I 1. Disconnect camshaft position (CMP) sensor (PHASE) harness connector. 2. Turn ignition switch ON. 3. Check the voltage between CMP sensor (PHASE) harness connector and ground. Is the inspection result normal? YES >> GO TO 9. NO-1 >> P0340: Repair open circuit or short to ground or short to power in harness or connectors. NO-2 >> P0345: GO TO 4. 4. CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY CIRCUIT-II 1. Turn ignition switch OFF. 2. Disconnect ECM harness connector. 3. Check the continuity between CMP sensor (PHASE) harness connector and ECM harness connector. Is the inspection result normal? YES >> GO TO 5. NO >> Repair open circuit. 5. CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY CIRCUIT-III Check harness for short to power and short to ground, between the following terminals.
