SFI SYSTEM(w/o EGR 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.

MONITOR DESCRIPTION

These DTCs are 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 on (IG) or the engine is running, the ECM will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN


  1. Turn the power switch on (IG) and wait for 5 seconds or more.

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. READ OUTPUT DTC (DTC P0010)


    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.

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

    6. Turn the power switch on (IG) and wait 5 seconds.

    7. Turn the GTS on.

    8. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.

    9. Read the DTCs.

  3. 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.

      Standard Resistance
      Tester Connection Condition Specified Condition
      C37-1 - C48-74 (OC1+) Always Below 1 Ω
      C37-2 - C48-75 (OC1-) Always Below 1 Ω
