DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P034031 Camshaft Position Sensor "A" Bank 1 or Single Sensor No Signal A missing camshaft position sensor signal despite the crankshaft position sensor inputs being normal at an engine speed of 600 rpm or higher (1 trip detection logic).

  • Open or short in camshaft position sensor circuit (for intake camshaft)

  • Camshaft position sensor (for intake camshaft)

  • Intake camshaft

  • ECM

 Comes on DTC stored SAE: P0340

MONITOR DESCRIPTION

When the VV1 signal is not input while the engine is running, the ECM illuminates the MIL and stores a DTC.

MONITOR STRATEGY

Required Sensors/Components (Main) Camshaft position sensor
Required Sensors/Components (Related) Crankshaft position sensor
Frequency of Operation Continuous

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 10 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: P034031.

  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.

CAUTION / NOTICE / HINT

Tech Tips


  • If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.

  • 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. CHECK TERMINAL VOLTAGE (POWER SOURCE OF CAMSHAFT POSITION SENSOR)

    Tech Tips

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

      (to Camshaft Position Sensor for Intake Camshaft)

      Disconnect the camshaft position sensor for intake camshaft connector.

    2. Turn the engine switch on (IG).

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      C25-3 (VC) - Body ground Engine switch on (IG) 4.5 to 5.5 V
      C25-1 (VVI+) - Body ground Engine switch on (IG) 3.0 to 5.5 V

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

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      C25-3(VC) - C25-1(VV1+) Engine switch off 1.425 to 1.575 kΩ
      C25-2 (VVI-) - Body ground Always Below 1 Ω

      *a OK
      *b NG
      *c Clearance

      Check the camshaft position sensor for intake camshaft installation.

      OK
      Camshaft position sensor for intake camshaft does not have any damage and is installed properly.

  3. INSPECT CAMSHAFT (TIMING ROTOR)


    1. Check the timing rotor of the intake camshaft.

      OK
      Camshaft timing rotor does not have any cracks or deformation.

      Tech Tips

      Perform "Inspection After Repair" after replacing the intake camshaft.
