MONITOR DESCRIPTION

When the engine is running and no crankshaft position sensor signal is received for 0.05 seconds or more, the ECM determines that the crankshaft position sensor circuit is malfunctioning and stores a DTC.

MONITOR STRATEGY

Required Sensors/Components (Main)

Crankshaft position sensor

Required Sensors/Components (Related)

Camshaft position sensor

CONFIRMATION DRIVING PATTERN

HINT:

  • After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

    Click here

  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

    Click here

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the GTS on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the ignition switch off and wait for at least 30 seconds.
  6. Start the engine [A].
  7. Run the engine at an engine speed of 1000 rpm for 5 seconds or more [B].
  8. Turn the GTS on.
  9. Enter the following menus: Powertrain / Engine / Trouble Codes [C].
  10. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  12. Proceed to the next screen and enter the DTC to be checked.
  13. 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

    HINT:

    • 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 steps [A] through [C] again.
    • [A] to [C]: Normal judgment procedure.

      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

    • When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT

HINT:

  • 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 ignition switch to ON.
    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 crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft 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 DTC OUTPUT (DTC P03351F AND P033511, P033515 OR P033531)

(a) Read the DTCs.

Powertrain > Engine > Trouble Codes

Result

Proceed to

DTC P03351F is output

A

DTC P03351F and P033511, P033515 or P033531 are output

B

HINT:

If DTC P033511, P033515 or P033531 is output, perform troubleshooting for those DTCs first.
