DESCRIPTION

HINT:
  1. This DTC relates to the Camshaft Timing Oil Control Valve (OCV).

The Variable Valve Timing (VVT) system includes the ECM, OCV and VVT controller. The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil pressure applied to the VVT controller. Camshaft timing control is performed according to engine operating conditions such as the intake air volume, throttle valve position and engine coolant temperature. The ECM controls the OCV, based on the signals transmitted by several sensors. The VVT controller regulates the intake camshaft angle using oil pressure through the OCV. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control. This is how the target intake valve timing is verified by the ECM.

INSPECTION PROCEDURE

HINT:
Read freeze frame data using an intelligent tester. 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.

1.CHECK WHETHER DTC OUTPUT RECURS (DTC P0010)

  1. Connect an intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the tester on.

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

  1. Clear DTCs.

  1. Start the engine and warm it up.

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

  1. Read DTCs.

2.INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    A200906E01

  1. Remove the OCV.

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		20°C (68°F)
    		6.9 to 7.9 Ω

  1. Apply battery voltage to terminals of the OCV. Check the valve operation.

    OK:
    Valve moves quickly.

  1. Reinstall the OCV.

3.CHECK HARNESS AND CONNECTOR (OCV - ECM)


    A200900E01

  1. Disconnect the OCV connector.

  1. Disconnect the ECM connector.

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

    Standard Resistance (Check for Open):
    Tester Connection
    		Condition
    		Specified Condition
    C7-1 (OC1+) - B8-97 (OC1+)
    		Always
    		Below 1 Ω
    C7-2 (OC1-) - B8-96 (OC1-)
    		Always
    		Below 1 Ω

    Standard Resistance (Check for Short):
    Tester Connection
    		Condition
    		Specified Condition
    C7-1 (OC1+) or B8-97 (OC1+) - Body ground
    		Always
    		10 kΩ or higher
    C7-2 (OC1-) or B8-96 (OC1-) - Body ground
    		Always
    		10 kΩ or higher
