MONITOR STRATEGY

Required Sensors/Components (Main) Crank position sensor
Required Sensors/Components (Related) Camshaft position sensor
Frequency of Operation Continuous

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG).

  3. Turn the GTS on.

  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  5. Turn the engine switch off and wait for at least 30 seconds.

  6. Start the engine.

  7. Idle the engine for 20 seconds or more.

  8. Run the engine at an engine speed of 1000 rpm for 5 seconds or more.

  9. Turn the GTS on.

  10. Enter the following menus: Powertrain / Engine / Trouble Codes.

  11. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  13. Input the DTC: P03351F, P03352A or P033531.

  14. Check the DTC judgment result.

    GTS Display Description
    NORMAL
    • DTC judgment completed

    • System normal

    ABNORMAL
    • DTC judgment completed

    • System abnormal

    INCOMPLETE
    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    Tech Tips


    • If the judgment result is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system has a malfunction.

    • If the judgment result is INCOMPLETE, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

Tech Tips


  • If no problem is found by this diagnostic troubleshooting procedure, check for problems by referring to the engine mechanical section.

  • The engine speed can be checked by using the GTS. To perform the check, follow the procedures below:


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Data List / Engine Speed.

    5. Start the engine.


    • The engine speed may be indicated as zero despite the engine running normally. This is caused by a lack of NE signals from the crank position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crank position sensor output voltage is insufficient.

  • Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. CHECK ENGINE


    1. Check the engine cranking condition.

      Result
      Result Proceed to
      Cranking is OK A
      Does not crank at all* B

      Tech Tips

      *: When the engine cannot crank, there may be a malfunction in the starter assembly.

  2. READ VALUE USING GTS (ENGINE SPEED)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Data List / Engine Speed.


      Powertrain > Engine > Data List
      Tester Display
      Engine Speed
    5. Start the engine.

    6. Read the values displayed on the GTS while the engine is running.

      Standard
      Correct values are displayed.

      Tech Tips


      • To check the engine speed change, display the graph on the GTS.

      • If the engine does not start, check the engine speed while cranking.

      • If the engine speed indicated on the GTS remains at zero (0), there may be an open or short in the crank position sensor circuit.
