Hi Andrew. Thanks for sending your question today. Typically this Toyota-specific OBD-II trouble code is due to an internal leak in the actuator circuit and the accumulator circuit. The first step in diagnosing this problem is verifying that there are no visible leaks in the system. If there are no leaks in the system then replacing the actuator and accumulator will resolve the issue.
