ECD SYSTEM (w/ 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 pickup coil. The sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of an iron core and magnet. The sensor plate rotates, and a pulse signal is created as each tooth passes by the pickup coil. The pickup coil generates 34 signals for each revolution. Based on these signals, the ECM calculates the crankshaft position and engine speed. Using these calculations, the common rail injection system is controlled.

P0335
DTC Detection Drive Pattern DTC Detection Condition Trouble Area
Crank or start engine

When the following condition is met (for 5 seconds during cranking or 0.5 seconds during engine start) (1 trip detection logic):

No crankshaft position sensor signal is sent to the ECM while cranking.


  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • No. 1 crankshaft position sensor plate

  • ECM

P0339
DTC Detection Drive Pattern DTC Detection Condition Trouble Area
Engine running at 1000 rpm or more with vehicle stationary

No crankshaft position sensor signal is input to the ECM for 0.05 seconds or more, and conditions (a), (b) and (c) are met (1 trip detection logic):


  • (a) Engine speed is 1000 rpm or more.

  • (b) STA signal is off.

  • (c) 3 seconds or more have elapsed after STA signal is switched from on to off.


  • Open or short in crankshaft position sensor circuit

  • Crankshaft position sensor

  • No. 1 crankshaft position sensor plate

  • Camshaft timing pulley

  • ECM

INSPECTION PROCEDURE

Note


  • After replacing the ECM, the new ECM needs registration Click here and initialization Click here.

  • After replacing the fuel supply pump assembly, the ECM needs initialization Click here.

  • After replacing an injector assembly, the ECM needs registration Click here.

Tech Tips


  • Read freeze frame data using the GTS. 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.

  • The Data List item Engine Speed is calculated from the output of the crankshaft position sensor.

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

PROCEDURE


  1. INSPECT CRANKSHAFT POSITION SENSOR


    1. Inspect the crankshaft position sensor Click here.


    NG
    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
      D79-1 - D99-103 (NE+) Always Below 1 Ω
      D79-2 - D99-102 (NE-) Always Below 1 Ω
      D79-1 or D99-103 (NE+) - Body ground Always 10 kΩ or higher
      D79-2 or D99-102 (NE-) - Body ground Always 10 kΩ or higher
    4. Reconnect the crankshaft position sensor connector.

    5. Reconnect the ECM connector.


    NG
    OK
  3. CHECK CRANKSHAFT POSITION SENSOR (SENSOR INSTALLATION)


    1. A003GE7E01

      Check the sensor installation.

      OK
      Sensor is installed correctly.

    NG
    OK
  4. CHECK NO. 1 CRANKSHAFT POSITION SENSOR PLATE


    1. Check the teeth of the sensor plate.

      OK
      The sensor plate teeth do not have any cracks or deformation.

    NG
    OK
  5. INSPECT CAMSHAFT TIMING PULLEY


    1. Check the teeth of the camshaft timing pulley.

      OK
      The sensor plate teeth do not have any cracks or deformation.

    NG
    OK

  12. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Connect the GTS to the DLC3.

    2. Clear the DTCs Click here.

    3. Turn the ignition switch off for 30 seconds or more.

    4. Start the engine and run it at 1000 rpm or more for 5 seconds or more.

    5. Confirm that the DTC is not output again.
