Camshaft Position "B" Actuator Circuit / Open (Bank 1)
DTC
P0023
Camshaft Position "B" Actuator Circuit / Open (Bank 2)
DESCRIPTION
This DTC is designed to detect opens or shorts in the camshaft oil control valve (OCV) circuit. If the
OCV 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 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 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.

MONITOR 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.

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 [A].
6.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].
7.
Read the Pending DTCs.
