SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P001313

DTC Code DTC Name
P001313 Camshaft Position "B" - Actuator Bank 1 Circuit Open

DESCRIPTION

The Variable Valve Timing (VVT) system (for exhaust side) adjusts the exhaust valve timing to improve driveability. The engine oil pressure turns the VVT controller (camshaft timing exhaust gear assembly) to adjust the valve timing.

The cam timing oil control solenoid assembly operates according to signals received from the ECM to control the position of the camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) and supply engine oil. The camshaft timing oil control valve assembly (exhaust camshaft timing gear bolt assembly) moves when the ECM applies 12 V to the cam timing oil control solenoid assembly. The ECM changes the energizing time of the cam timing oil control solenoid assembly (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.

P001313 Camshaft Position "B" - Actuator Bank 1 Circuit Open Open or short in cam timing oil control solenoid assembly circuit (1 trip detection logic).

  • Open or short in cam timing oil control solenoid assembly circuit

  • Cam timing oil control solenoid assembly

  • ECM

 Comes on DTC stored SAE Code: P0013

MONITOR DESCRIPTION

This DTC is designed to detect an open or short in the cam timing oil control solenoid assembly circuit. If the cam timing oil control solenoid assembly duty-cycle is excessively high or low while the engine 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 engine 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 engine switch off and wait for at least 30 seconds.

  6. Start the engine.

  7. Wait 5 seconds or more.

  8. Turn the GTS on.

  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: P001313.

  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

    Tech Tips


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

    • If the judgment result is ABNORMAL, the system has a malfunction.

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 engine switch on (IG).

    3. Turn the GTS on.

    4. Clear the DTC after recording the Freeze Frame Data and DTC.

  2. READ OUTPUT DTC (DTC P001313)


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

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

    5. Read the DTCs.
