DESCRIPTION

This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the OCV's duty-cycle is excessively high or low while the engine is running, the ECM will illuminate the MIL and set the DTC.
The Variable Valve Timing (VVT) system adjusts the exhaust valve timing to improve the driveability. The engine oil pressure turns the camshaft actuator to adjust the valve timing. The OCV is a solenoid valve and switches the engine oil line. The valve moves when the ECM applies the 12 volts 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.

INSPECTION PROCEDURE

УКАЗАНИЕ:
  1. If DTC P0013 is displayed, check the bank 1 VVT system for exhaust side circuit.
  2. Bank 1 refers to the bank that includes No. 1 cylinder.
  3. If DTC P0023 is displayed, check the bank 2 VVT system for exhaust side circuit.
  4. Bank 2 refers to the bank that does not include No. 1 cylinder.
  5. 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.

1.CHECK DTC (DTC P0013 OR P0023)

  1. Connect the intelligent tester to the DLC3.

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

  1. Turn the engine switch off.

  1. Allow the engine to idle and check DTC.

  1. Check that P0013 or P0023 is present.

    OK:
    P0013 or P0023 is present

2.INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    A095415E03

  1. Disconnect the E12 or E17 OCV connector.

  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

3.CHECK HARNESS AND CONNECTOR (OCV - ECM)


    A149432E01

  1. Disconnect the E12 or E17 OCV connector.

  1. Disconnect the E2 and E4 ECM connectors.

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

    Standard resistance (Check for open):
    Tester Connection
    		Condition
    		Specified Condition
    E12-1 - E2-4 (OE1+)
    		Always
    		Below 1 Ω
    E12-2 - E2-3 (OE1-)
    		Always
    		Below 1 Ω
    E17-1 - E4-18 (OE2+)
    		Always
    		Below 1 Ω
    E17-2 - E4-28 (OE2-)
    		Always
    		Below 1 Ω

    Standard resistance (Check for short):
    Tester Connection
    		Condition
    		Specified Condition
    E12-1 or E2-4 (OE1+) - Body ground
    		Always
    		10 kΩ or higher
    E12-2 or E2-3 (OE1-) - Body ground
    		Always
    		10 kΩ or higher
    E17-1 or E4-18 (OE2+) - Body ground
    		Always
    		10 kΩ or higher
    E17-2 or E4-28 (OE2-) - Body ground
    		Always
    		10 kΩ or higher
