DESCRIPTION

The crankshaft position sensor system consists of a crankshaft position sensor plate and Magneto-Resistive Element (MRE) type sensor. The crankshaft position sensor plate has 34 teeth at 10° intervals (2 teeth are missing for detecting top dead center), and is installed on the crankshaft. The crankshaft position sensor generates 34 signals per crankshaft revolution. The ECM uses the NE signal to detect the crankshaft position and engine speed.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • ECM

 Comes on DTC stored SAE: P0337
P033515 Crankshaft Position Sensor "A" Circuit Short to Battery or Open The crankshaft position sensor output voltage is higher than 4.7 V for 4 seconds or more (1 trip detection logic).

  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • ECM

 Comes on DTC stored SAE: P0338

MONITOR DESCRIPTION

If the output voltage transmitted by the crankshaft position sensor remains low or high, the ECM interprets this as a malfunction in the sensor circuit, illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the power 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 power switch off and wait for at least 30 seconds.

  6. Turn the power switch on (IG).

  7. Turn the GTS on.

  8. Put the engine in Inspection Mode (2WD for measuring Exhaust Gas).

    Click here

  9. Start the engine.

  10. Idle the engine for 20 seconds or more [A].

  11. Enter the following menus: Powertrain / Engine / Trouble Codes [B].

  12. Read the pending DTCs.

    Tip:

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

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

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

  14. Input the DTC: P033511 or P033515.

  15. 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
    Tip:

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

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

    • If the judgment result shows INCOMPLETE, perform steps [A] and [B] again.

CAUTION / NOTICE / HINT

Note:

  • Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

    (Select Powertrain in Health Check and then check the time stamp data.)

    Click here

  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

Tip:

  • 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 power switch on (IG).

    3. Turn the GTS on.

    4. Put the engine in Inspection Mode (2WD for measuring Exhaust Gas).

      Click here

    5. Start the engine.

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


    • 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.

    READ VALUE USING GTS (ENGINE SPEED)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Put the engine in Inspection Mode (2WD for measuring Exhaust Gas).


      1. Powertrain > Hybrid Control > Utility
        Tester Display
        Inspection Mode




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


      1. Powertrain > Engine > Data List
        Tester Display
        Engine Speed




    6. Start the engine.

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

      Standard
      Correct values are displayed.
      Tip:

      • 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 crankshaft position sensor circuit.

    CHECK HARNESS AND CONNECTOR

    Tip:

    Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.


    1. Disconnect the crankshaft position sensor connector.

    2. Turn the power switch on (IG).

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
