Hello, my name is***** most likely means the bank 1 camshaft actuator has failed. Failure to advance the camshaft could be caused by a faulty cam adjuster, a faulty cam adjuster solenoid, low oil pressure, sludged oil passages, or a sticky camshaft. I would recommend replacing the actuator/solenoid as it is probably sticking. Let me know how it goes or if you have more questions, thanks.
