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
store the DTC.
- The VVT (variable valve timing) system adjusts the intake and exhaust
valve timing to improve 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 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.

- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON and turn the Techstream on.
- Wait 5 seconds.
- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
- Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
- Input the DTC: P0013 or P0023.
- Check the DTC judgment result.

1. | CHECK FOR DTC (DTC P0013 OR P0023) |
(a) Connect the Techstream to the DLC3. (b) Clear DTCs after recording the freeze frame data and DTC.
(c) Turn the ignition switch off. (d) Allow the engine to idle and check for DTCs.
(e) Check that P0013 or P0023 is not present. OK: P0013 or P0023 is not present.
