SFI SYSTEM, Diagnostic DTC:P0010

DTC Code DTC Name
P0010 Camshaft Position "A" Actuator Circuit (Bank 1)

DESCRIPTION

The Variable Valve Timing (VVT) system adjusts the intake valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.

The camshaft timing oil control valve assembly is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies 12 V to the solenoid. The ECM changes the energizing time to the solenoid (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.

DTC No. DTC Detection Condition Trouble Area
P0010

Open or short in camshaft timing oil control valve (for intake camshaft) circuit

(1 trip detection logic)

  • Open or short in camshaft timing oil control valve assembly (for intake camshaft) circuit

  • Camshaft timing oil control valve assembly (for intake camshaft)

  • ECM

MONITOR DESCRIPTION

This DTC is designed to detect open or short in the camshaft timing oil control valve assembly (for intake camshaft) circuit. If the camshaft timing oil control valve's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and store the DTC.

The monitor for this DTC runs 5 seconds after the ignition switch is turned to ON.

CONFIRMATION DRIVING PATTERN


  1. Connect the intelligent tester to the DLC3.

  2. Turn the ignition switch to ON and turn the tester on.

  3. Clear DTCs (even if no DTCs are stored, perform the clear DTC operation)

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

  5. Turn the ignition switch to ON and turn the tester on.

  6. Wait 5 seconds or more.

  7. Enter the following menus: Powertrain / Engine and ECT / DTC.

  8. Read 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.

  9. Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.

  10. Input the DTC: P0010.

  11. Check the DTC judgment result.

    Tester 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 shows NORMAL, the system is normal.

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

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

CAUTION / NOTICE / HINT

Tech Tips


  • If DTC P0010 is output, check the VVT system (for intake camshaft) circuit.

  • Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. 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 FOR DTC


    1. Connect the intelligent tester to the DLC3.

    2. Clear the DTCs after recording the freeze frame data and DTCs.

    3. Turn the ignition switch off.

    4. Start the engine and allow it to idle. Then check for DTCs.

    5. Check that P0010 is not output.

      OK
      P0010 is not output.

    OK

  3. CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY (FOR INTAKE CAMSHAFT) - ECM)


    1. Disconnect the camshaft timing oil control valve assembly (for intake camshaft) connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance
      for LHD
      Tester Connection Condition Specified Condition
      B63-1 - B22-75 (OC1+) Always Below 1 Ω
      B63-2 - B22-74 (OC1-) Always Below 1 Ω
      B63-1 or B22-75 (OC1+) - Body ground Always 10 kΩ or higher
      B63-2 or B22-74 (OC1-) - Body ground Always 10 kΩ or higher
      for RHD
      Tester Connection Condition Specified Condition
      B63-1 - B23-75 (OC1+) Always Below 1 Ω
