Diagnosis Procedure

  1. CHECK GROUND CONNECTION 
    1. Turn ignition switch OFF.
    2. Check ground connection M95. Refer to Ground Inspection in CIRCUIT INSPECTION .

      Is the inspection result normal? 

      YES: GO TO  2.

      NO: Repair or replace ground connection.

  2. CHECK CRANKSHAFT POSITION (CKP) SENSOR POWER SUPPLY CIRCUIT-I 
    1. Disconnect CKP sensor harness connector.
    2. Turn ignition switch ON.
    3. Check the voltage between CKP sensor harness connector and ground.
