SFI SYSTEM, Diagnostic DTC:P034011, P034015

DTC Code DTC Name
P034011 Camshaft Position Sensor "A" Bank 1 or Single Sensor Circuit Short to Ground
P034015 Camshaft Position Sensor "A" Bank 1 or Single Sensor Circuit Short to Battery or Open

DESCRIPTION

The camshaft position sensor (VV1 signal) consists of a magnet and MRE (Magneto Resistance Element).

The intake camshaft has a timing rotor for the camshaft position sensor. When the intake camshaft rotates, changes occur in the air gaps between the timing rotor and MRE, which affects the magnetic field. As a result, the resistance of the MRE material fluctuates. The camshaft position sensor converts the camshaft rotation data to pulse signals, uses the pulse signals. The ECM uses the pulse signals to determine the camshaft angle. Then the ECM uses this data to control fuel injection duration and injection timing.

  • Open or short in camshaft position sensor circuit

  • Camshaft position sensor

  • ECM

 Comes on DTC stored SAE Code: P0342
P034015 Camshaft Position Sensor "A" Bank 1 or Single Sensor Circuit Short to Battery or Open The camshaft position sensor output voltage is higher than 4.7 V for 4 seconds or more (1 trip detection logic).

MONITOR DESCRIPTION

If the output voltage transmitted by the camshaft position sensor remains low or high, the ECM interprets this as a malfunction in the sensor circuit, illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG).

  3. Turn the GTS on.

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

  5. Turn the power switch off and wait for at least 30 seconds.

  6. Turn the power switch on (IG).

  7. Turn the GTS on.

  8. Put the engine in Inspection Mode (Maintenance Mode).

  9. Start the engine.

  10. Idle the engine for 10 seconds or more.

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

  12. 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.

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

  14. Input the DTC: P034011 or P034015.

  15. 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
    N/A

    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system is malfunctioning.

    • If the judgment result is INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

Note


  • Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

    (Select Powertrain in Health Check and then check the time stamp data.)

  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

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 HARNESS AND CONNECTOR

    Front view of wire harness connector

    (to 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.


    1. Disconnect the camshaft position sensor connector.

    2. Turn the power switch on (IG).

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      C19-3 (VC) - Body ground Power switch on (IG) 4.5 to 5.5 V
      C19-1 (VVI+) - Body ground Power switch on (IG) 3.0 to 5.0 V

    4. Turn the power 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 Condition Specified Condition
      C19-3 (VC) - C19-1 (VVI+) Power switch off 1.425 to 1.575 kΩ
