SFI SYSTEM(w/o Canister Pump Module), Diagnostic DTC:P001013

DTC Code DTC Name
P001013 A Camshaft Position Actuator Bank 1 Circuit Open

DESCRIPTION

The Variable Valve Timing (VVT) system consists of the ECM, camshaft timing oil control valve assembly and camshaft timing gear assembly.

The VVT system controls the camshaft timing oil control valve assembly to operate the camshaft timing gear assembly and optimize the intake valve timing according to driving conditions. This control is performed based on the air flow volume, throttle position, engine coolant temperature, etc. Based on signals from each sensor, the ECM controls the position of the camshaft timing control valve assembly to change the relative position of the camshaft, enhance the engine torque and fuel economy and decrease the exhaust gas emissions. Using signals from the camshaft position sensor, the ECM detects the actual valve timing and performs feedback control to optimize the valve timing.

P001013 A Camshaft Position Actuator Bank 1 Circuit Open Open or short in camshaft timing oil control valve assembly circuit (1 trip detection logic).
  • Open or short in camshaft timing oil control valve assembly circuit

  • Camshaft timing oil control valve assembly

  • ECM

Comes on DTC stored SAE Code: P0010

MONITOR DESCRIPTION

This DTC is designed to detect an open or short in the camshaft timing oil control valve assembly circuit. If the camshaft timing oil control valve assembly duty-cycle is excessively high or low while the power switch is on (IG) or the engine is running, the ECM will illuminate the MIL and store this 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. Wait 5 seconds or more.

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

  10. 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.

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

  12. Input the DTC: P001013.

  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

    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.

Tech Tips

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. CLEAR DTC


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTC after recording the freeze frame data and DTC.


      Powertrain > Engine > Clear DTCs
    5. Turn the power switch off and wait for at least 30 seconds.

  2. READ OUTPUT DTC (DTC P001013)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

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

  4. CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM)


    1. Disconnect the camshaft timing oil control valve assembly connector.

    2. Disconnect the ECM connector.

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