DESCRIPTION

The camshaft position sensor (for intake camshaft) (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.

MONITOR DESCRIPTION

If the output voltage transmitted by the camshaft position sensor (for intake camshaft) 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 ignition switch to ON.

  3. Turn the GTS on.

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

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

  6. Turn the ignition switch to ON.

  7. Turn the GTS on.

  8. Wait 5 seconds or more.

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

  10. 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.

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

  12. Input the DTC: P034011 or P034015.

  13. 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
    Tip:

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

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

CAUTION / NOTICE / HINT

Tip:

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.

    CHECK HARNESS AND CONNECTOR

    Tip:

    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 (for intake camshaft) connector.

    2. Turn the ignition switch to ON.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      C18-3 (VC) - Body ground Ignition switch ON 4.5 to 5.5 V
      C18-1 (VVI+) - Body ground Ignition switch ON 3.0 to 5.0 V

    4. Turn the ignition 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
      C18-3 (VC) - C18-1 (VVI+) Ignition switch off 1.425 to 1.575 kΩ
      C18-2 (VVI-) - Body ground Ignition switch off Below 1 Ω
