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 "WORK FLOW (WITH GR8-1200 NI) " or "WORK FLOW (WITHOUT GR8-1200 NI) ". For the details of the GR8-1200 NI, refer to "SPECIAL SERVICE TOOLS ".).

  2. CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY 
    1. Turn ignition switch OFF.
    2. Disconnect camshaft position (CMP) sensor (PHASE) harness connector.
    3. Turn ignition switch ON.
    4. Check the voltage between CMP sensor (PHASE) harness connector and ground.
      + - Voltage (Approx.)
      CMP sensor (PHASE)
      Connector Terminal
      F109 1 Ground 5 V

      Is the inspection result normal? 

      YES: GO TO  4.

      NO: GO TO 3.

  3. CHECK SENSOR POWER SUPPLY CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check harness connector for short to power and short to ground, between the following terminals.
      ECM Sensor
      Connector Terminal Name Connector Terminal
      F25 39 FRP sensor F5 1
      EOP sensor F43 3
      Turbocharger boost sensor F75 1
      F26 68 Battery current sensor F52 1
      G sensor B32 3
      72 CMP sensor F109 1
      EVT control position sensor F110 1
      E18 118 APP sensor 2 E101 5

      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 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between CMP sensor (PHASE) harness connector and ECM harness connector.
      + - Continuity
      CMP sensor (PHASE) ECM
      Connector Terminal Connector Terminal
      F109 2 F26 59 Existed
    4. Also check harness for short to power.

      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Repair or replace error-detected parts.

  5. CHECK CMP SENSOR (PHASE) INPUT SIGNAL CIRCUIT 
    1. Disconnect ECM harness connector.
    2. Check the continuity between CMP sensor (PHASE) harness connector and ECM harness connector.
      + - Continuity
      CMP sensor (PHASE) ECM
      Connector Terminal Connector Terminal
      F109 3 F26 63 Existed
    3. Also check harness for short to ground and to power.

      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 "COMPONENT INSPECTION ".

    Is the inspection result normal? 

    YES: GO TO 7.

    NO: Replace camshaft position sensor (PHASE). Refer to "REMOVAL AND INSTALLATION ".

  7. CHECK CAMSHAFT (INT) 

    Check the following.

    • Accumulation of debris to the signal plate of camshaft rear end
    • Chipping signal plate of camshaft rear end

      Is the inspection result normal? 

      YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

      NO: Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to "REMOVAL AND INSTALLATION ".
