Code P265B Description

The Engine Control Module (ECM) commands the Rocker Arm Actuator to control the oil hydraulic circuit. Oil flows through the Rocker Arm Actuator to the variable valve timing system to adjust the engine's valve timing. The variable valve timing (VVT) system is used to improve engine's performance, fuel economy or emissions. The ECM monitors the 'B' Rocker Arm Actuator Position Sensor and sets the OBDII when the 'B' Rocker Arm Actuator Position Sensor signal is out of factory specifications.
