ECD SYSTEM(w/o DPF), Diagnostic DTC:P0335, P0339

DTC Code DTC Name
P0335 Crankshaft Position Sensor "A" Circuit
P0339 Crankshaft Position Sensor "A" Circuit Intermittent

DESCRIPTION

The crankshaft position sensor system consists of a crankshaft position sensor plate and a pickup coil.

The sensor plate has 58 teeth and is installed on the crankshaft. The pickup coil is made of an iron core and a magnet. The sensor plate rotates and as each tooth passes through the pickup coil, a pulse signal is created.

The pickup coil generates 58 signals per engine revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the common rail system is controlled.

Tech Tips


  • If DTC P0335 and/or P0339 is stored, the following symptoms may appear:


    • Difficult to start

    • Engine stalls due to fail-safe operation (fuel cut)

CAUTION / NOTICE / HINT

Note

When replacing the ECM and/or engine assembly, the ECM needs Registration and Initialization Click here.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the intelligent tester. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the tester display.

  • Check the value on the intelligent tester.


    1. Connect the intelligent tester to the DLC3.

    2. Start the engine and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed.

  • The engine speed can be confirmed in the Data List using the intelligent tester. If there are no NE signals from the crankshaft position sensor despite the engine revolving, the engine speed will be indicated as zero. If the voltage output of the crankshaft position sensor is insufficient, the engine speed will be indicated as lower than the actual engine rpm.

  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. INSPECT CRANKSHAFT POSITION SENSOR


    1. Inspect the crankshaft position sensor Click here.


    NG

    REPLACE CRANKSHAFT POSITION SENSOR Click here

    OK

  2. CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)


    1. Disconnect the crankshaft position sensor connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      B94-1 - B21-19 (NE+) Always Below 1 Ω
      B94-2 - B21-18 (NE-) Always Below 1 Ω
      B94-1 or B21-19 (NE+) - Body ground Always 10 kΩ or higher
      B94-2 or B21-18 (NE-) - Body ground Always 10 kΩ or higher

      Tech Tips

      A DTC may also be stored when the ground of a shielded wire is faulty.


    NG

  3. CHECK SENSOR INSTALLATION (CRANKSHAFT POSITION SENSOR)


    1. A01VJNTE02
      Text in Illustration
      *a Normal
      *b Abnormal
      *c Clearance

      Check the crankshaft position sensor installation.

      OK
      Sensor is installed correctly.

    NG

    SECURELY REINSTALL SENSOR Click here

    OK

  4. INSPECT NO. 1 CRANKSHAFT POSITION SENSOR PLATE (TEETH OF SENSOR PLATE)


    1. Inspect the teeth of the sensor plate.

      OK
      Sensor plate does not have any cracks or deformation.

    NG
