Camshaft Position "A" Actuator Circuit (Bank 2)
DESCRIPTION
This DTC is designed to detect opens or shorts in the Camshaft Timing Oil Control Valve Assembly (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 VVT (variable valve timing) system adjusts the intake 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 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.

CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on.
5.
Wait 5 seconds.
6.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
7.
Read Pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
8.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
9.
Input the DTC: P0010 or P0020.
10.
Check the DTC judgment result.
