SFI SYSTEM(w/ GPF), Diagnostic DTC:P033511, P033515

DTC Code DTC Name
P033511 Crankshaft Position Sensor "A" Circuit Short to Ground
P033515 Crankshaft Position Sensor "A" Circuit Short to Battery or Open

DESCRIPTION

The crankshaft position sensor system consists of a crank angle sensor plate and Magneto-Resistive Element (MRE) type sensor. The crank angle 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.

MONITOR DESCRIPTION

When the crankshaft position sensor voltage is higher or lower than the threshold, the ECM stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

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

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

  5. Turn the engine switch on (IG) and turn the GTS on.

  6. Start the engine.

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

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

  9. 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.

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

  11. Input the DTC: P033511 or P033515.

  12. 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 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.

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. Start the engine.

    3. Turn the GTS on.

    4. 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.

PROCEDURE


  1. 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 crankshaft position sensor circuit.

  2. CHECK HARNESS AND CONNECTOR

    Tech Tips

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