P265A Meaning
The Engine Control Module (ECM) commands the rocker arm actuator to control the hydraulic oil circuit. Oil flows through the rocker arm actuator to the variable valve timing system to adjust engine valve timing. The Variable Valve Timing (VVT) system is used to improve engine performance, fuel economy, or emissions. The ECM monitors the rocker arm actuator position sensor “B” and sets the OBDII code when the rocker arm actuator position sensor “B” signal is outside factory specifications.
