DTC P0013: Camshaft Position "B" Actuator Circuit / Open (Bank 1); DTC P0023: Camshaft Position "B" Actuator Circuit / Open (Bank 2) [11/2016 - ]: Description

WARNING: This page is about a different variant/trim than selected.

The Variable Valve Timing (VVT) system adjusts the exhaust valve timing to improve driveability. The engine oil pressure turns the VVT controller to adjust the valve timing.

The cam timing oil control solenoid assembly operates according to signals received from the ECM to control the position of the camshaft timing oil control valve assembly and supply engine oil. The camshaft timing oil control valve assembly moves when the ECM applies 12 V to the cam timing oil control solenoid assembly. The ECM changes the energizing time of the cam timing oil control solenoid assembly (duty-cycle) in accordance with the camshaft position, crankshaft position, throttle position, etc.
