What does code P2654 mean?

Q: What does code P2654 mean?

'B' Rocker Arm Actuator Control Circuit High (Bank 1). P2654 indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the control circuit for the 'B' rocker arm actuator on bank 1 of the engine. This actuator is part of a variable valve timing or cylinder deactivation system that adjusts rocker arm operation to optimize performance and efficiency. The high voltage condition suggests a short to power, an open circuit, or a faulty actuator, and the PCM may disable the system and illuminate the check engine light.
