DTC P0013: Camshaft Position "B" Actuator Circuit / Open (Bank 1); DTC P0023: Camshaft Position "B" Actuator Circuit / Open (Bank 2) [10/2014 - ]: 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.
