DTC Diagnosis Procedure
- 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
- Disconnect camshaft position (CMP) sensor (PHASE) harness connector.
- Turn ignition switch ON.
- Check the voltage between CMP sensor (PHASE) harness connector and ground.
