OBD II Fault Code
- OBD II P2655
OBD-II Code Decreased engine performance is defined as a "A" Rocker Arm Actuator Control Circuit/Open
Newer vehicles use variable valve technology to allow for greater airflow through the engine at higher RPMs. This allows for better performance over a wider range. Some manufacturers are moving to a variable valve lift system that allows the valve to open wider. Internal to the variable lift rocker arm assembly are position sensors so the engine computer (PCM) can monitor what the assembly is doing. If the solenoid inside the assembly fails, code P2655 is set.
