DESCRIPTION

The crankshaft position sensor system consists of a crankshaft position sensor plate (crankshaft pulley) and Magneto Resistance 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.

MONITOR DESCRIPTION

A DTC will be stored if any of the following occurs:

  • The crankshaft position sensor signal (NE signal) is not received by the ECM when the engine is being cranked.

  • The crankshaft position sensor signal (NE signal) is not received by the ECM when the engine is running.

  • The engine stalls and the engine speed signal value decreases rapidly (under normal conditions the engine speed will decrease gradually).

  • The crankshaft position sensor output voltage is above or below the threshold.

CONFIRMATION DRIVING PATTERN

  1. Connect the GTS to the DLC3.

  2. Turn the ignition switch to ON and turn the GTS on.

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

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

  5. Turn the ignition switch to ON and turn the GTS on.

  6. Start the engine.

  7. Idle the engine for 20 seconds or more.

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

  9. 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.

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

  11. Input the DTC: P033511, P033515, P03351F, P03352A or P033531.

  12. Check the DTC judgment result.

    • DTC judgment completed

    • System normal

    ABNORMAL

    • DTC judgment completed

    • System abnormal

    INCOMPLETE

    • DTC judgment not completed

    • Perform driving pattern after confirming DTC enabling conditions

    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
    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 or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

CAUTION / NOTICE / HINT

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 ignition switch to ON.

    3. Turn the GTS on.

    4. Start the engine.

    5. Enter the following menus: Powertrain / Engine / Data List / All Data / 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 ignition switch to ON.

    3. Turn the GTS on.

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

      OK

      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 zero (0), there may be an open or short in the crankshaft position sensor circuit.
